Part IV: The Melting Pot - Anglo-Saxons, Vikings, and Normans

The Middle Ages (c. 500 - 1500 AD) was a period of successive migrations that layered upon the Romano-British foundation, creating the ethnolinguistic groups that persist today. The subject's DNA from this era tells a story of this complex mixing.

Insular Celt (63.2%): After the withdrawal of Roman legions, the native Romano-British population remained the genetic bedrock of the island. This majority component represents those ancestors who would form the medieval kingdoms of Wales, as well as those who were gradually assimilated into the emerging English kingdoms. This is the genetic signature of the Welsh Prewett line and also represents the underlying British substrate within the English Harris line.

Viking/Germanic/Baltic (13.4%): This component captures the major migrations of the era. It includes the Angles, Saxons, and Jutes who founded England; the Vikings who raided and settled the Danelaw; and other North Sea peoples who maintained constant contact. This DNA is a direct link to the migrations that transformed Britain's language and culture, forming a key part of the Harris family's English heritage.

French & Iberian (23.4%): This significant component primarily reflects the influence of the Norman Conquest in 1066. The new Norman aristocracy, themselves of mixed Norse and Frankish origin, brought a new ruling class and language to England. Over centuries, they intermarried with the local Anglo-Saxon and British population at all levels of society. This DNA points to ancestors who were part of this new Anglo-Norman world, linking the family tree to the continent in the medieval period.

Part III: Britannia - Life on the Edge of an Empire

The Roman occupation of Britain (AD 43 - 410) was a period of cultural transformation but not of mass genetic replacement. The DNA from this time reveals the persistence of the native population alongside a subtle influx from across the Empire.

Roman Britain (27.4%): This component reflects the continuation of the native Iron Age gene pool. "Roman Britain" refers to the Celtic Britons living under Roman rule.

Germanic (19.0%): The Germanic component continues from the Iron Age, likely bolstered by the Roman practice of using Germanic auxiliaries (foederati) to help defend the province's borders, particularly the "Saxon Shore" forts of Kent.

Pictish (17.2%): Represents the related but distinct tribes in unconquered Caledonia (modern Scotland).

Gallo-Roman (14.6%): Points to soldiers, administrators, merchants, and their families who came to Britain from Gaul (France).

Hispano-Roman (9.4%): Indicates presence of people from Hispania (Spain) in Britain during the Roman period.

Part II: The Age of Hillforts - A Celtic British Landscape

The Iron Age (c. 800 BC - AD 43) was the period immediately preceding the Roman conquest, a time when Britain was a tapestry of Celtic-speaking tribes. The ancestral makeup from this era reveals the complex origins of these peoples.

Continental Celt (29.6%): This component reflects the initial waves of Celtic-speaking peoples who migrated from mainland Europe, likely starting in the late Bronze Age and continuing into the Iron Age.

Insular Celtic (34.4%): This represents the genetic signature of those Celtic populations after they had settled in the British Isles for generations.

Germanic (22.6%): The presence of a significant Germanic component *before* the Anglo-Saxon period points to substantial and continuous contact, trade, and migration across the North Sea.

Part I: The Deep Past - Foundations of a European Genome

The story of any individual's ancestry is a narrative woven from countless threads, stretching back through recorded history into the deep past. For Li Jean-Luc Harris, this narrative begins not in the fields of Kent or the valleys of Wales, but tens of thousands of years ago, culminating in the great prehistoric migrations that defined the genetic landscape of Europe. The analysis of the subject's DNA reveals a foundational heritage rooted in three major streams of ancient peoples whose movements and interactions created the very bedrock upon which all subsequent European populations, including those of the British Isles, were built.

The deepest layer of the subject's genetic makeup is composed of 50.0% Central Steppe, 40.4% European Farmer, and 9.6% Bronze Age Caucasian. Each represents a distinct ancestral population and a pivotal chapter in the peopling of the continent.

The European Farmer component (40.4%) connects to the first great demographic revolution in European history: the advent of agriculture. These Neolithic pioneers from Anatolia brought farming to Europe and remain a foundational element in all modern Europeans.

The Central Steppe component (50.0%) represents the single largest piece of this ancestral puzzle, signifying a connection to a vast migration of nomadic pastoralists from the Pontic-Caspian Steppe. In Britain, this stream is linked to the "Beaker People," who arrived around 2500 BC and profoundly altered the island's gene pool, spreading the ancestral lineages that would eventually give rise to Celtic and other Indo-European languages.

The final component, Bronze Age Caucasian (9.6%), is an echo from a more ancient crossroads. This DNA was a key ingredient in the formation of the Steppe pastoralists themselves, meaning it arrived in Europe as part of that migratory package—a genetic signature of a much older mixing event in the Eurasian heartland.
