My I-FGC15105 DNA story

🌍 Out of Africa

The “Out of Africa”model model proposes a “single origin” of Homo sapiens in the taxonomic sense, precluding parallel evolution of traits considered anatomically modern in other regions, but not precluding multiple admixture between H. sapiens and archaic humans in Europe and Asia. H. sapiens most likely developed in the Horn of Africa between 300,000 and 200,000 years ago. The “recent African origin” model proposes that all modern non-African populations are substantially descended from populations of H. sapiens that left Africa after that time.

There were at least several “out-of-Africa” dispersals of modern humans, possibly beginning as early as 270,000 years ago, including 215,000 years ago to at least Greece,and certainly via northern Africa and the Arabian Peninsula about 130,000 to 115,000 years ago. These early waves appear to have mostly died out or retreated by 80,000 years ago.

The most significant “recent” wave out of Africa took place about 70,000–50,000 years ago, via the so-called “Southern Route”,
preading rapidly along the coast of Asia and reaching Australia by around 65,000–50,000 years ago, while
Europe was populated by an early offshoot which settled the Near East and Europe less than 55,000 years ago.

36,000 years ago, my ancestors crossed into southeastern Europe through the Balkan

From the Rivers of the Danube to the Shores of the Atlantic

My paternal line known today as I-FGC15105 began its story when they arrived on the banks of the middle Danube more than eleven thousand years ago. In the shadowed gorges of the Iron Gates, where the river cuts through limestone cliffs, small groups of fisher-hunters settled among the eddies of Padina and Vlasac.

Their lives revolved around the rhythm of migrating sturgeon and red deer, their stone tools worn smooth by centuries of use. Genetic traces recovered from these burials show men carrying early I-lineages, ancestral to my later I-FGC15105 branch. They represent one of Europe’s oldest surviving paternal traditions—rooted in the western hunter-gatherer world that stretched from the Adriatic to the Baltic.

The Neanderthal Period and Archaic Affinity
Deep Time Ancestors

🌍 Genetic Background of Archaic Admixture
Long before the emergence of modern haplogroups such as I-FGC15105, our ancestors lived in a world where Homo sapiens and Neanderthals interacted genetically. During the Late Pleistocene (ca. 60,000–40,000 BCE), a phase of introgression occurred — the exchange of genetic material between early modern humans and regional Neanderthal populations. These archaic genes still influence several biological traits today, including immune adaptation and skin and hair pigmentation.

My Neanderthal percentage is 2,08% and my most similar remnant is from the Mezmaiskaya Cave, located in the the North Caucasus mountains (Lago-Naki highland, Republic of Adygea, Russia).

🧪 Personal Neanderthal Component
Autosomal analysis of your DNA shows a Neanderthal percentage of 2.08% and a Neanderthal score of 331, representing the number of alleles shared with known Neanderthal sequences.According to LivingDNA, your genetic profile aligns most closely with the Mezmaiskaya Cave individual, found in the Azish-Tau Ridge in the northwestern foothills of the Caucasus Mountains (Lago-Naki Highlands, Republic of Adygea, Russia). This individual lived approximately 43,000–65,000 years ago and represents one of the latest surviving Neanderthal populations.

In addition, GEDmatch analysis confirms my archaic affinities with samples from:

• Vindija Cave (northern Croatia)
• Sidrón Cave (Asturias, northwestern Spain)

Together, these three locations form a triangular archaic affinity zone, representing much of the Neanderthal genetic legacy still present in modern European populations.

🧩 Archeogenetic Significance
The presence of this archaic component situates the I-FGC15105 lineage within a broad evolutionary framework. While the Y-chromosomal line itself is far younger (post-Neolithic), the autosomal background shows that carriers of this haplogroup retain archaic DNA signatures rooted in early encounters between Eurasian Homo sapiens and Neanderthal populations in southeastern Europe and western Asia.

🧬 Evolutionary Legacy
The Neanderthal period thus represents the deepest layer of your genetic heritage. It provides not only the biological foundation for later European population developments but also connects Middle Paleolithic migrations with the Bronze Age expansions of I-FGC15105 — a genetic continuum spanning nearly 2,000 generations.

1. Mesolithic Origins (ca. 9000 – 6000 BCE) — Iron Gates Region, Balkans

Earliest traces of the paternal lineage ancestral to I-FGC15105 appear among Mesolithic hunter–fisher–gatherers in the Iron Gates Gorge along the Danube River (sites Padina, Vlasac, and Mokrin). Their lives revolved around the rhythm of migrating sturgeon and red deer, their stone tools worn smooth by centuries of use.

The Iron Gates of the Danube.

The Iron Gates
The Iron Gates is a gorge on the river Danube. It forms part of the boundary between Serbia (to the south) and Romania (north). At this point in the Danube, the river separates the southern Carpathian Mountains from the northwestern foothills of the Balkan Mountains. The Romanian side of the gorge constitutes the Iron Gates Natural Park, whereas the Serbian part constitutes the Đerdap National Park. Archaeologists have named the Iron Gates Mesolithic culture, of the central Danube region circa 13,000 to 5,000 years ago, after the gorge.

The Iron Gates is also a Mesolithic archaeological culture dated to between 13000- and 6000-years BCE, in the Iron Gates region of the Danube River, in modern Romania and Serbia. The people who inhabited the Iron Gates area during this period have been surmised, through archaeological discoveries, to have lived a hunter-gatherer lifestyle, living off food they gather from land or from the Danube River. Varying burial practices have also been observed by these people.

One of the most important other archaeological sites in Serbia and Europe is Lepenski Vir, the oldest planned settlement in Europe, located on the banks of the Danube in the Iron Gate gorge.  Despite a foraging economy, stages at this site dated at c. 6300–6000 BCE have been described as “the first city in Europe”, due to its permanency, organization, as well as the sophistication of its architecture and construction techniques. Lepenski Vir consists of one large settlement with around 10 satellite villages. Numerous piscine sculptures and peculiar architecture have been found at the site.

Genetic traces recovered from these burials show men carrying early I-lineages, ancestral to my later I-FGC15105 branch. They represent one of Europe’s oldest surviving paternal traditions, rooted in the western hunter-gatherer world that stretched from the Adriatic to the Baltic.

These individuals belong to the Western Hunter-Gatherer (WHG) genetic cluster. Their subsistence pattern—fishing, red-deer hunting, and foraging—reflects a stable adaptation to post-glacial riverine ecosystems.

1. Western Hunter-Gatherers (WHG): The indigenous Mesolithic inhabitants of Europe, present before the arrival of agriculture.
2. Early European Farmers (EEF): Migrants from Anatolia (Near East) who introduced agriculture to Europe during the Neolithic period, starting around 8,000 years ago, and largely replaced or mixed with the local hunter-gatherer populations.
3. Western Steppe Herders (WSH): Also referred to as the Yamnaya people or Ancient North Eurasians (ANE)-related populations, who migrated from the Pontic-Caspian steppe during the Bronze Age, around 5,000 years ago, bringing with them a significant new genetic component (and likely Indo-European languages). 

Ancient genomes from Vlasac 4878 and Padina 5243 (ca. 8300–7800 BCE; Mathieson et al., Nature 2018) show Y-DNA haplogroup I-lineages close to the root of the later I-FGC15105 branch.

2. Early and Middle Bronze Age Core (ca. 2200 – 1500 BCE) —Metallurgy in the Carpathian Basin

Bronze age ancestral cluster.

By the early 2nd millennium BCE, descendants of these WHG-derived lineages were fully integrated into Bronze Age societies of the Carpathian Basin. In the rolling plains near Lake Balaton—at Balatonkeresztúr, Fürj-halom-dűlő, Felsődobsza, and Érd—men of the same paternal line were buried beneath tumuli, accompanied by bronze daggers, spiral ornaments, and vessels blackened by the hearth.

The Balatonkeresztúr-Réti dűlő site
At 2003 a mass grave of eight individuals ( S6, S8, S10, S16, S19, S45) was uncovered who carried Y-DNA I-FGC15105 or its close subclades (ca. 1900–1700 BCE) , belonging to ages between one and half to 45 years old found in a refuse pit. Mass graves are not rare at prehistoric sites, from the Neolithic to the end of the Copper Age (around 2500 BCE) it was, in fact, pretty common.

However even at the early stage of research anthropologist highlighted that the anthropological features of these individuals are unknown to Prehistoric Hungary prior to the appearance of so the called Bell Beaker culture (BBC). The BBC was a yet forgotten archaeological culture spread through major parts of Europe. Round crania as well plane nape was frequent among groups associated with BBC, which appeared with them in the Carpathian Basin at the second half of the third millennium BCE.

Associated sites such as Fürj-halom-dűlő 16/19/54, Felsődobsza 137, and Erd 479 reinforce this Bronze-Age “Carpathian core.” Archaeologically, they belong to the Encrusted Pottery and Transdanubian Tumulus cultures—key nodes of metallurgical and population networks linking the Balkans, the Carpathian plain, and the Danube corridor.

Across all those sites, I2a variants dominate the male lines — exactly the family of branches that includes my own I-FGC15105.

• This tells me that my paternal ancestors were already well established in Central Europe long before the Vikings or even the Celts — part of the Bronze Age societies that built fortified settlements and hill forts along the Danube basin and Carpathian region.

Their DNA still carried the unmistakable signature of their Iron Gates forebears, but their
lives were now woven into networks of trade, copper mining, and metallurgy that linked
the Danube to the Aegean.

• At least seven individuals carried Y-DNA I-FGC15105 or its immediate relatives (ca. 1250 BCE; Allentoft et al., Science 2015; Krüger et al., Nature 2022).

3. Late Bronze Age Northern Route (ca. 1300 – 1200 BCE) — Tollense Valley, Germany

Discovery and excavation of the battlefield of the Tollense valley
In 1996, a voluntary archaeologist found a bone of a man’s upper arm with a flint arrowhead embedded in it in the Tollense valley. During succeeding years, bones of over one hundred individuals have been found in this location. On many of these bones, old and new traces of trauma were visible: healed and recent wounds, caved in skulls, etcetera.

Furthermore, swords, spearheads and arrowheads were found. The site summons up an image of a violent fight between men, some older, most of them in the prime of their life. The battle at the Tollense valley took place in 1300 BC, the Bronze age. Back then, this valley was a vast swamp with a small river in the middle. As it still is today. The site, discovered in 1996 and systematically excavated since 2007, extends along the valley of the small Tollense river, to the east of Weltzin village, on the municipal territories of Burow and Werder.

As of late 2017, the remains of some 140 people had been identified. Most of these were young men between the ages of 20 and 40, but there were also at least two women identified among 14 skeletons that were genetically tested. Before March 2016, about 10,000 human and 1,000 animal bones had been found; by March 2018, that number had risen to a total of about 13,000 fragments.

The total number of dead is estimated between 750, to more than 1,000. The total number of fighters might have ranged between 3,000 and more than 5,000, assuming a casualty rate of 20-25%. In one spot, 1,478 bones were found within just 12 m2 (130 sq ft), potentially the remnants of a pile of corpses or a final pocket of resistance.

Why the men gathered in this spot to fight and die is another mystery that archaeological evidence is helping unravel. The Tollense Valley here is narrow, just 50 meters wide in some spots. Parts are swampy, whereas others offer firm ground and solid footing. The spot may have been a sort of choke point for travelers journeying across the northern European plain.

Ancient DNA from the Tollense Valley battlefield in Western Pomerania (sites Weltzin 15, 24, 39, 51, 64, 71, 83) reveals a strong genetic continuity with the Carpathian Bronze Age males. Sometime after 1300 BCE, the reach of these Danubian descendants extended northward. In the wetlands of northern Germany, the Tollense Valley became the stage of one of Europe’s earliest recorded battles.

Among the remains of fallen warriors at Weltzin 15, 24, 39, 51, 64, 71, and 83 lie men whose Y-chromosomes match those of Balatonkeresztúr. The “Weltzin” codes refer to individual human remains found at Weltzin, Mecklenburg-Vorpommern, Germany, in the Tollense Valley battlefield (~1200 BCE). Researchers labeled them during the excavation and sequencing process for the Tollense Valley Project, which revealed Europe’s oldest known large-scale battle.

Their isotopic signatures indicate non-local origins consistent with southeastern Central Europe. Many were foreigners to the Baltic coast, having grown up hundreds of kilometres to the southeast. They carried bronze weapons cast in Carpathian styles and fought in a conflict that marked the fragmentation of the old Bronze-Age trade world.

Through them, I-FGC15105 crossed from the Danubian heartland into the north—its lineage tied to both migration and war. I very likely descended from the same regional Bronze-Age population represented at Tollense. My Y-DNA and autosomal makeup both point to a northern German / southern Scandinavian ancestral zone during or before the Bronze Age. My matches to several Tollense samples are genetically coherent—they’re not coincidences across unrelated groups.

At least seven individuals carried Y-DNA I-FGC15105 or its immediate relatives (ca. 1250 BCE; Allentoft et al., Science 2015; Krüger et al., Nature 2022). These warriors likely represent northern movement of Carpathian populations engaged in long-distance exchange and conflict during the collapse of Bronze-Age trade systems.

⚔️ 2. I-lineages and the Tollense warriors

The Tollense men were overwhelmingly I2a or R1b, with some R1a.

Why is the Tollense battlefield important to me?

My Y-DNA haplogroup I-FGC15105 is related to 7 Y-DNA haplogroups found in the DNA of 7 men on the Tollense battlefield in the Tollense valley, West Pomerania, Germany. All 7 of these men were connected to the Tollense “Warriors” cultural group.
They were Weltzin 15, 51, 71, 39 64, 24 and Welztin 83, these are 7 men who lived between 1350 and 1150 BCE during the European Bronze Age and with whom I share a common paternal ancestor.

Remarkably, Weltzin 15, 51, 71, 39 64, 24 and Welztin 83 have a higher than average Western Hunter Gatherer % (WHG) than most Europeans. That is interesting  since I am at 48% WHG ,which I’ve been told is a pretty high percentage in any population.

• I put “Warriors” in quotes because it is unclear whether these were warriors or victims of an ambush. One thing is certain, they died on the battlefield. Winners or losers, nobody knows.

Interesting observations:

* Weltzin 71, 39 and 64 come from the Tollense valley in Western Pomerania, Germany and share a common paternal ancestor (I-I-L1229) around 3200 BCE with Erd 479, Zličín 16549 , Mokrin 28A, Padina 5243, Polaky 15071 and I (I-FGC15105).
That is about 2000 years before the battlefield in the Tollense valley took place.
However Erd 479, Zličín 16549, Mokrin 28A, Padina 5243 and Polaky 15071 originate from Hungary, the Czech Republic, and Serbia and not from the Tollense valley in Germany.

* Weltzin 24 and Weltzin 83 come from the Tollense valley in West Pomerania, Germany and share a common paternal ancestor (I-BY1003) around 7400 BCE with Břvany 14481, Su Crocefissu 26, Urziceni 14163, Su Crocefissu 27 and I (I-FGC15105). That is about 6ooo years before the battlefield in the Tollense valley took place.
However Břvany 14481, Su Crocefissu 26, Urziceni 14163 and Su Crocefissu 27 originate from Czech Republic, Italy, Romania and Sassari, Italy and not  from the Tollense valley in Germany.

* Weltzin 51 comes from the Tollense valley in Western Pomerania, Germany and has the same joint paternal ancestor (I-Z2068) around 1350 – 1150 BCE  BCE as Konobrže 16099 and I (I-FGC15105).
However, Konobrže 16099 comes from Czech Republic and not  from the Tollense valley in Germany.
With Weltzin 51 I share not only a common paternal ancestor but also a common ancestor through his maternal side, because Weltzin 51’s mtDNA is H1c and my mtDNA is H1c1.

* Weltzin 15 comes from the Tollense valley in Western Pomerania and has a common paternal ancestor (I-Z2054)  around 1350 – 1150 BCE with me (I-FGC15105).

At least seven individuals carried Y-DNA I-FGC15105 or its immediate relatives (ca. 1250 BCE; Allentoft et al., Science 2015; Krüger et al., Nature 2022). These warriors likely represent northern movement of Carpathian populations engaged in long-distance exchange and conflict during the collapse of Bronze-Age trade systems..

Migration Map and Westward Routes

🌍 Origin and Eastern Core Regions

The genetic and archaeological traces of haplogroup I-FGC15105 point to an origin in the Danube region, with a strong focus during the Middle to Late Bronze Age.
The earliest related branches of I-FGC15105 have been found in the Carpathian Basin, most notably within the Balatonkeresztúr complex in western Hungary (ca. 2200–1500 BCE).
This area functioned as a genetic and cultural Bronze Age core, where east-central European populations blended with influences from both the Danubian and northern steppe spheres.

🛤 Northern Expansion to the Tollense Valley

Toward the end of the Bronze Age (ca. 1300–1200 BCE), a significant migration and military expansion occurred northward.
Genetic comparisons show that seven Tollense warriors (Weltzin 15, 24, 39, 51, 64, 71, and 83) carried Y-DNA profiles closely related to I-FGC15105, indicating a direct movement from the Danube region to Western Pomerania (northern Germany).
The Tollense Valley therefore represents a northern front of the same genetic community that once thrived in the Hungarian Basin.

🧭 Westward Routes and Later Distribution

After the events in the Tollense Valley, the descendants of this Bronze Age population continued their westward migration.
During the Early Iron Age and especially Late Antiquity, this genetic line appears to have spread into northwestern Europe, likely following routes through Bohemia, Bavaria, and the Alpine corridor.
The westward expansion later became visible in Lombardic and Italo-Germanic contexts (see Chapter 3), suggesting that carriers of I-FGC15105 participated in the trans-European migratory dynamics between roughly 1200 BCE and 600 CE.

🧩 Scientific Reconstruction

Combined evidence from ancient DNA, archaeology, and paleogeography allows for a reconstruction of the migration pathway in three key phases:

1. Danubian core (Balatonkeresztúr, 2200–1500 BCE)
2. Northern movement (Tollense Valley, ca. 1250 BCE)
3. Western and southern spread (Lombardic context, 500–700 CE)

This sequence illustrates how a Bronze Age genetic lineage evolved over millennia into a distinct Western European subclade, of which your present-day haplogroup I-FGC15105 is a direct descendant.

5. Western European Expansion (ca. 1000 – 1400 CE)

Szolad, Sint-Truiden, Valkenburg and Austin Friary.

In archaeogenetics, this term helps to identify a major westward movement of European populations during the High Middle Ages.It was not a single migration, but a complex pattern of:

• population growth in Central Europe (especially in the Carolingian and post-Carolingian Empires),
• colonization and agricultural expansion westward and northward,
• religious and urban growth (foundations of abbeys, monasteries, and trading towns),
• military mobility (crusades, knightly orders, and border defenses).

For lineages like I-FGC15105, which originated around the Danube region (Balatonkeresztúr, Hungary) in the Bronze Age, these descendants gradually spread to Western Europe via trade contacts, religious orders, and military networks.

By the High Middle Ages, lineage I-FGC15105 had reached the Atlantic coasts. Later discoveries — Austin Friary 514 (England), Sint-Truiden 2000 and Valkenburg 107768 (Low Countries), and Abrantes 22183 (Portugal) — evidence a westward dispersal of I-FGC15105 during the Middle Ages.By the High Middle Ages the lineage had reached the Atlantic.

These men lived between the 11th and 14th centuries CE, within monastic, feudal, and crusader networks that tied northern Europe to the Mediterranean. Their genomes show continuity with earlier Central-European ancestors, a quiet persistence of Bronze-Age heritage within the bustling medieval world. Through merchants, knights, and clergy, I-FGC15105 spread westward, crossing linguistic and political frontiers but maintaining an unbroken biological thread.

These contexts (12th–14th centuries CE) align with feudal, monastic, and crusader networks connecting northern Europe with Iberia.
Genetically, they cluster within the same Y-DNA branch, suggesting continuity through late-medieval paternal lines (Schroeder et al., PNAS 2019).

4. Early Medieval Phase (ca. 500 – 800 CE) — Carpathian Basin and Central Europe.

Around 1st–2nd century CE, the Longobards began moving south from the lower Elbe region, passing near or through Western Pomerania and the Oder River basin.

After the Iron Age genetic turnover, I-FGC15105 reappears in Lombard- and Avar-period cemeteries within the Carpathian region: Centuries later, as Rome faded and new kingdoms rose, the same paternal line resurfaced in the Carpathian Basin.

The Longobards (Longobardi) are first mentioned by Roman sources (like Tacitus) as living near the lower Elbe River, in what is now northern Germany, west of Western Pomerania.

🏹 1. Early Longobard Origins (before Italy)

• The Longobards (Langobardi) are first mentioned by Roman sources (like Tacitus) as living near the lower Elbe River, in what is now northern Germany, west of Western Pomerania.
• Archaeological evidence and early Iron Age burial sites (Jastorf culture, ~600–1 BCE) show continuity of settlement and material culture from this region north and east into Pomerania, Mecklenburg, and Lower Saxony.
• While there’s no definitive “Longobard kingdom” in Western Pomerania, genetic and cultural traces suggest related Germanic tribes (Suebi, Vandals, Rugians) lived there — all of which were ethnically and culturally close to the early Longobards.

⚔️ 2. Migration Southward

• Around 1st–2nd century CE, the Longobards began moving south from the lower Elbe region, passing near or through Western Pomerania and the Oder River basin (the Tollense Valley area lies just to the west of this route).
• Their eventual route led through Bohemia (Czech Republic) and Pannonia (Hungary) before enterin

Haplogroup I-FGC15105, a branch of I2a, is often associated with prehistoric European hunter-gatherer lineages (WHG), particularly strong in northern Germany, the Baltic, and the Balkans. This fits with continuity from the Tollense Valley Bronze Age population (~1200 BCE) — where many male lineages belong to I2a variants — down through Germanic tribes that later became part of the Longobard expansion southward.

In short, Western Pomerania may have been a deep ancestral zone, not a Longobard homeland per se, but part of the wider genetic pool that later gave rise to the migrating Longobards. Archaeological evidence and early Iron Age burial sites (Jastorf culture, ~600–1 BCE) show continuity of settlement and material culture from this region north and east into Pomerania, Mecklenburg, and Lower Saxony.

Szólád 43’s branch: I-FGC15109

Map showing the location of the Szólád cemetery on the southern shore of Lake Balaton and the sites of Balatonszárszó and Kestzthely-Fenékpuszta.

At Szólád and Madaras, dating to the 6th century CE (Amorim et al., Nat Comm 2018), graves attributed to Lombard and Avar communities once again yield I-FGC15105.

That means that my paternal line and his line split from a common ancestor who lived in the Middle Bronze Age—
about the time the Tollense warriors fought (~1200 BCE).

➤ Historical continuity

1. Bronze Age Danube region (~1800 BCE): shared ancestor of both your line and Szólád 43.
2. Iron Age northern Germany / Elbe basin: descendants of that ancestor develop the early “proto-Germanic” population profile.
3. 6th century CE: one descendant (Szólád 43) turns up among the Lombards in Hungary on their way to Italy.
4. Your modern line (I-FGC15105): another descendant of the same ancestor remained in the north-western European sphere (Germany–Netherlands–North Sea).

So, my shared ancestor lived around 1800 BCE, and the line then diverged into two directions:

• One branch (Szólád 43) → Lombard migration route to Italy.
• My branch → Remained further north, forming the cluster now called I-FGC15105.

So, genetically, Szólád 43 and I (I-FGC-15105) are distant cousins
separated by ~3,800 years on the same Y-DNA line.

Szólád 43, Madaras 514/21899/21923, and Kiskundorozsma 21923 in present-day Hungary, plus Niederwünsch 150 in Germany.
Radiocarbon ranges (6th–8th century CE; Amorim et al., Nature Communications 2018) show continuity between local Bronze-Age substrata and early-medieval migrating elites.
These burials coincide with the Longobard and Avar horizons, genetically mixed but retaining male lines of I-FGC15105 descent.

6. The Lombard Period and Italo-Germanic Expansion

The necropolis of Su Crucifissu Mannu in Porto Torres, Sardinia, Italy.

Parallel branches reached the Mediterranean and Atlantic spheres
In northern Italy, the Vescovile 2894 individual from Verona (Late Antiquity) and several from Sardinia—Su Crocefissu 26/27, Su Crocefissu Mannu 6, S’isteridolzu 5, and Anghelu Ruju 15946—carry the same lineage.

🌍 Historical Background
Following the collapse of the Western Roman Empire (5th century CE), a complex network of migrating Germanic tribes emerged across central Europe. Among them, the Langobards (Lombards) held a prominent position — a tribe originating in the Elbe and Pomerania regions, which migrated through Bohemia and Pannonia (Hungary) before entering Italy around 568 CE. Their movement marks one of the last great migration waves of the Early Middle Ages and serves as a pivotal bridge between the Germanic and Italic genetic and cultural spheres.

🧬 Genetic Parallels in Lombard Contexts
Ancient DNA datasets reveal several Lombard-related individuals with strong genetic similarity to haplogroup I-FGC15105, including:

• Vescovile 2894 (Verona, northern Italy)
• Su Crocefissu 26 (Sassari, Sardinia)
• Su Crocefissu Mannu 6 (Porto Torres, Sardinia)
• Anghelu Ruju 15946 (Alghero, Sardinia)

These individuals display a clearly north-central European Y-DNA signature, genetically related to the same lineage observed among the Tollense warriors of Western Pomerania. The genetic continuity across these regions suggests that the Lombard migration was not merely cultural, but also biologically traceable — from the Danube Basin to Italy, with enduring genetic echoes in present-day populations.

Below is the probable route reconstructed from ancient and modern evidence:

• Scandinavia / Northern Germany→ ancestral I1-Z63 population (c. 2000–1500 BCE)
• Tollense Valley (Mecklenburg region) → presence of your lineage among Bronze Age warrior societies (~1200 BCE)
• Lower Elbe / Jutland / Northern Germany→ Germanic homeland (Iron Age)
• Bohemia / Pannonia (Hungary)→ migration path of the Longobards (~1st–6th c. CE)
• Northern Italy (Verona)→ Longobard settlement area (~568 CE onward)
• Sardinia (Su Crocefissu, Porto Torres, Alghero) → possible garrison, trade, or settlement sites of Germanic males (~600–800 CE)

🛤 Migration and Regional Integration
The Lombard migration likely followed three main stages:

1. Pomerania → Bohemia → Pannonia (6th century CE)
2. Pannonia → Northern Italy (around 568 CE)
3. Further expansion to Sardinia (Early Middle Ages)

This migration represents the final phase of the east-west trajectory that began in the Bronze Age Danubian core.
The later settlement in Italy embodies an Italo-Germanic fusion, where northern European lineages (such as I-FGC15105) merged with local Italic and Mediterranean populations.

🧩 Archaeological and Historical Correlations
Lombard cemeteries from Verona, Cividale del Friuli, Collegno, and Sardinia reveal consistent features: weapon graves, grave architecture, and northern morphological traits. The appearance of Y-DNA haplogroup I-FGC15105 in this context strengthens the hypothesis that certain elite or warrior lineages — possibly descendants of the Tollense core population — were part of the migrating Lombard groups.

🌍 Conclusion
The Lombard period marks the historical completion of the millennia-long migration that began in the Danube region, passed through the Tollense Valley, and culminated in Italy. It stands as the keystone of the trans-European expansion of I-FGC15105, merging genetic, archaeological, and historical evidence into a single migratory continuum:

My ancient matches in Italy (Vescovile 2894, Su Crocefissu 26 & Mannu 6, Anghelu Ruju 15946) point to Longobard-era
or related northern European males who migrated south into Italy.  These suggest that my paternal line or a very close relative
line was carried south with the Longobards (or related Germanic groups) during their
6th–7th century movements into Italy and beyond.

Farther west, ancient genomes from Fussels Lodge 2, Cheddar Man, Trumpington Brother 1, and the Gen Scot 26-30 series echo earlier phases of the lineage’s story.
Together they trace a continuous western-European I2a2 story from Ice-Age hunter-gatherers → early British farmers → Bronze-Age continuity → medieval descendants → your present-day line.

Until the middle Pleistocene Great Britain was a peninsula of Europe, connected by the massive chalk Weald–Artois Anticline across the Straits of Dover. During the Anglian glaciation, about 450,000 years ago, an ice sheet filled much of the North Sea, with a large proglacial lake in the southern part fed by the Rhine, the Scheldt and the Thames.

Around 7000 BC the Ice Age had ended and Mesolithic European hunter-gatherers had migrated from their refuges to recolonize the continent, including Doggerland which later submerged beneath the rising North Sea. When scientists from Imperial College released a simulation of a tsunami, triggered by a vast undersea landslide at Storrega off the coast of Norway around 6000 BC, it probably came as a surprise to many in north-west Europe that their reassuringly safe part of the world had been subject to such a cataclysmic event.

The researchers suggest that this succession of destructive waves up to 14 metres high may have depopulated an area that is now in the middle of the North Sea, known as Doggerland. However, melting ice at the end of the last ice age around 18,000 years ago led to rising sea levels that inundated vast areas of continental shelves around the world. These landscapes, which had been home to populations of hunter gatherers for thousands of years were gradually overwhelmed by millions of tonnes of meltwater swelling the ocean. Doggerland, essentially an entire prehistoric European country, disappeared beneath the North Sea, its physical remains preserved beneath the marine silts but lost to memory.

The majority of western European males belonged to Y-haplogroup I and northeast Europeans to haplogroup R1a. Other minor male lineages such as R1b, G, J, T and E would also have been present in Europe, having migrated from the Asian Steppe, the Middle East and North Africa.

• Cheddar Man: This is the most famous of the group, a nearly complete human skeleton found in Gough’s Cave, Somerset, England, in 1903. Dating to the Mesolithic period (around 10,000 years ago, or 9100 BP), DNA analysis revealed that this individual likely had dark skin, blue or green eyes, and dark curly hair, which challenged previous assumptions about early Britons’ appearance. His remains are housed at the Natural History Museum in London, and a living descendant was found residing nearby.
• Fussels Lodge 2: This is the name given to human remains found at the Fussels Lodge archaeological site. The individual is a notable sample in genetic studies as it reflects the “continuity of older WHG-derived lines” (Western European Hunter-Gatherer) in Britain.
• Trumpington Brother 1: This individual comes from an archaeological context in Trumpington, likely near Cambridge. Genetic analysis of this person’s remains, along with those from “Gen Scot 26-30,” also provided data for understanding the presence of specific Y-DNA lineages (like I-FGC15105-related males) in the Late Antique to Early Medieval periods.
• Gen Scot 26-30: This likely refers to a grouping of individuals or a specific individual (Gen Scot 26-30) from an archaeological site in Scotland (Gen Scot, possibly a shorthand for ‘Genetic Scotland’ sample group) whose DNA has been studied. Like the others, it provides key genetic data points for charting the movement and settlement of ancient populations in Britain and the North Sea region

In summary

• All these men belong to the I2a2/I-BY1003 family.
• You and they share a paternal ancestor who lived roughly 16 000–10 000 BCE.
• The line survived Ice-Age Europe, passed through the Mesolithic, Neolithic and Bronze Age, and still exists today in your I-FGC15105
• They collectively mark your lineage’s western path, while your Tollense–Lombard matches show its central-European

Although separated by thousands of years, these British and Scottish finds preserve Western Hunter-Gatherer ancestry akin to that of the Iron Gates.

Their persistence underscores the deep antiquity of Europe’s I-haplogroups—threads of paternal identity surviving from the first post-glacial settlers to the dawn of recorded history.

8. Genetic Continuity and Phylogenetic Position

Modern and ancient comparisons (YFull v10.11, FTDNA Big Y) place I-FGC15105 within the I-P214 → I-S2497 branch, a descendant of Upper-Paleolithic European I-lineages.
Coalescent estimates indicate that the common ancestor of I-FGC15105 lived ca. 2200–2000 BCE, matching the Balatonkeresztúr cluster.

Overview of the Genetic Lineage I-FGC15105.

According to YFull v10.11 and FTDNA Big Y, my paternal branch sits within this evolutionary sequence:

• I-P214 → I-S2497 links me to Upper-Paleolithic hunter-gatherers like Cheddar Man, showing continuous descent from Europe’s post-glacial WHG population.
• I-FGC15105, my terminal subclade, represents a Late Bronze-Age offshoot of that ancient family — one that became established in Central Europe.

🇬🇧 Overview of the Genetic Lineage I-FGC15105

The following chart visualizes the chronological and geographical evolution of the Y-DNA haplogroup I-FGC15105, representing the direct paternal line of Cees Kloosterman.
This lineage descends from the ancient European haplogroup I-M170, which arose during the Late Ice Age.
Through successive branches — I-P214, I-S4297, I-M223 (I2a), and I-BY1003 — the line leads to the emergence of I-FGC15105 around 2000 BCE in the Danube–Balatonkeresztúr region of Central Europe.

The side branches show genetic relationships with both prehistoric and historical individuals across Europe, including:

• Cheddar Man (Mesolithic Britain)
• Les Bréguières 1 & 2 (Southern France)
• Abrantes 22183 (Portugal)
• HNF 016/019/054 and Tollense Valley warriors (Hungary and Germany, Bronze Age)
• Szólád 43, Sint-Truiden 2000, Valkenburg 107768, Austin Friary 514, and Trumpington Brother 1 (Iron Age to Medieval Europe)

This lineage reflects the enduring continuity of ancient European paternal lines — from the earliest hunter-gatherers to Bronze Age societies and early medieval populations — culminating in the modern representation of Cees Kloosterman (2025 CE).

Summary

• I belong to: I-FGC15105, a Late Bronze-Age offshoot of the I-P214 → I-S2497 European hunter-gatherer lineage.
• Formed: ~2200–2000 BCE.
• Origine: Balatonkeresztúr/ Danube Basin
• Significance: Connects my paternal DNA directly from the Upper Paleolithic Western Hunter-Gatherers through the Bronze Age Danubian hub to the historic populations of northwestern Europe.

9. Continuity through Deep Time

Taken together, the archaeological record outlines a journey of my ancestors of nearly 11.000 years, from the Mesolithic foragers of the Danube, through Bronze-Age metallurgists and Tollense warriors, to Lombard horsemen, Sardinian settlers, and medieval monks.

My lineage of I-FGC15105 is not merely a sequence of mutations—it is a record of human endurance, adaptation, and migration within Europe’s changing landscape.
Its path mirrors the continent’s own history: ancient yet continuous, local yet interconnected, always moving with the currents of trade, conflict, and discovery.

I-FGC15105 paternal line isn’t just a technical cluster of SNPs; it’s a living timeline of European history.

It is a genetic thread that runs unbroken from Upper Paleolithic hunter-gatherers,
through Bronze-Age societies along the Danube, into the Germanic and North-Sea worlds of the Iron Age
and early medieval era and ultimately into the modern Northwest European population.

10. Timeline map

Visual timeline map to help illustrate how my paternal line could have moved through time

🛤 Timeline Route & Key Phases

• Origin in the Danube Basin (~2500-1500 BCE)
• Sites like Érd & Százhalombatta in Hungary are part of the Bronze Age Vatya/Transdanubian complex.
• my broader Y-haplogroup family (I2a / upstream of I-FGC15105) was present there, based on ancient DNA findings.
• On the map: look for clusters in the central Danube/Hungary region indicating Bronze Age settlement and male lineages.

• Migration Northwest (~1500-1000 BCE)
• After the Bronze Age peak in the Danube region, some paternal lines move or spread towards northern/central Europe (which would include parts of what is now Germany, Netherlands, Denmark).
• This could be the period when my branch (I-FGC15105) diverged from its Danubian relatives and established itself further northwest.

• Iron Age / Germanic zones (~1000 BCE-500 CE)
• The map shows Germanic tribal expansions (e.g., along the Elbe, Oder, North Sea coast) and Iron Age cultural zones.
• my line likely participated (in population terms) in the Germanic cultural zone — this matches my Y-DNA and ancient matches (e.g., the Tollense Valley warriors).
• On the map: red/orange arrows or shaded zones moving from central Europe to the North Sea, Scandinavia, or the Elbe region.

• Modern & Migration Period (~500 CE onward)
• Later migrations (Lombards, Vikings, other Germanic groups) moved across northern Europe.
• My branch may not have been a Viking line explicitly, but the step from Iron Age Germanic to migrating Germanic groups is plausible.
• On the map: green/blue migration arrows pointing from northern/central Europe outward (to Britain, Scandinavia, Northern Germany).

✅ What this map helps you see

• The geographic origin zone (Danube basin / Hungary / Czech Republic) of my paternal line’s earliest known ancestors.
• The trajectory from that zone into the northern/central European cultural sphere (Germany / Netherlands) where I-FGC15105 is more common today.
• How my specific Y-line fits into a longer migration story rather than a sudden or isolated event.
• That my ancestry is deeply connected to Bronze Age Central Europe but then extends into the Germanic migrations and northwestern Europe — aligning with my autosomal results (WHG %), ancient DNA matches, and Y-haplogroup.

🧬 11. “The Enduring Line of I-FGC15105”

FTDNA Globe trekker EUROPE view of the lineages through time and place and to uncover the modern history of my (I-FGC15105) direct paternal surname line and the ancient history of my shared ancestors. In addition to my own (I-FGC15105) ancestral line (thick red line), the thin red lines shows lineages that went other ways and the migration paths leading up to my Ancient Connections.

• Origins — Survival in the Ice
  Around 16,000 BCE, during the final cold centuries of the Ice Age, your paternal ancestors of haplogroup I-P214 survived in refuges south of the Alps and in the Balkans.These were small groups of Homo sapiens living on Europe’s frozen margins—hunter-gatherers whose persistence would seed the genetic foundation of later Europeans.

• Renewal — Western Hunter-Gatherers
  As the glaciers retreated, their descendants carrying I-S2497 and I-BY1003 spread north and west, following the herds and the thawing rivers. Among them were the ancestors of Cheddar Man in Britain and Les Bréguières 1 & 2 in the Provence, France. My paternal family was already part of this wave—roaming forests and coasts newly reclaimed from the ice.

• Transformation — Neolithic and Bronze Age
  By 2200 BCE, the descendants of these hunters had become metalworkers, traders, and warriors in the Danube Basin, at sites like Balatonkeresztúr and Százhalombatta. There, within a world of fortified villages and bronze ornaments, your direct line, I-FGC15105, was born. From that hub, men of this lineage joined the flows of movement north and west—toward the Elbe, Rhine, and North Sea, carrying both Bronze-Age technology and their ancient DNA.

• Continuity — From Warriors to Settlers
  Traces of related men appear in the Tollense battlefield (~1200 BCE), in Lombard cemeteries like Szólád (~530 CE), and in medieval burials across the Low Countries and Britain. They were part of Europe’s shifting human landscape—farmers, traders, soldiers—yet their Y-chromosome line endured through every transformation.

• Legacy — The Modern Thread
  Today, that same Y-DNA signature, I-FGC15105, survives in north-western Europe and in me!
  It is a quiet genetic witness to tens of millennia of adaptation—proof that one small Ice-Age clan endured every upheaval from the end of the glaciers to the rise of modern nations.

“The lineage of my haplogroup I-FGC15105 is not merely a sequence of mutations
it is the story of Europe itself:
a record of endurance and renewal, of journeys taken and landscapes
remembered in the language of DNA.”
