It is now 440 CE in the Tas Valley of what is now called Norfolk, England. My 51-times great-grandmother is a young girl, playing in the ruins of the old city of Venta Icenorum. Other than squatters and salvage-hunters, the city has largely fallen into decay and is mostly deserted.
Her people are Romanistas - Romano-Britons. They are the Christian, Romanised Britons of the 5th century, and they have good reason to pray. It has been more than thirty years since the last legions departed Britannia. The shore forts stand derelict. The economy is in crisis, and their society is shattered.
Her father is a decurion, a local magistrate and landowner. He has witnessed the decline throughout his life. His tenants are restless, their economy still clinging to the memory of the coin, yet they scratch the heavy local soils with light ards that barely bite the earth.
But a new people are settling these lands, arriving from across the North Sea. Their culture is alien, having evolved free of imperial history. They are industrious workers and brave warriors. They use heavy iron-shod ploughs and brute strength to turn the stubborn clay soils. They rely on barter and tender—trading their surplus products rather than coinage.
The father is wise. He understands the value of cultivating a strong relationship with these new tenants, mercenaries, and trading partners. They may speak in rough Germanic tongues and worship pagan deities, but they promise a way out of the crisis. These are the early arrivals of a people known as the Angles. They have arrived as mercenaries and pioneers, and have brought a dearth of brides. My 51-times great-grandmother was always destined for an arranged marriage.
Her father had made a wise decision. Her husband's family proved they knew how to get the best out of these difficult soils. Their imported culture inspired the local Romano-Britons; by leading through example, they became the new leaders of the valley.
This AI image visualises the aging couple. They sit at home in a comfortable Anglo-Saxon house. I've asked for a cross section to demonstrate the earth pit basement below the wooden floor. These features left archaeological traces known as SFB (sunken feature building).
Cultures often change, but those who work the soil frequently remain. This underplayed rule applies more so to the women—a rule that can be observed through the mtDNA record.
Rationale
Recent genomic studies—most notably the 2022 Gretzinger et al. study—suggest a significant genetic turnover in Eastern England, with up to 74% of the ancestry in areas like Norfolk being attributed to Continental Northern European populations.
At first, this sounds like support for the old 'mass Anglo-Saxon invasion' story of Hengist and Horsa. However, the researchers stress that this immigration event was spread over as much as 600 years, from the early mercenaries up to and including the 9th and 10th-century Danish (Viking) farmers. This represents a long, drawn-out North Sea Immigration Continuum.
Therefore, integration was often a more peaceful process, occurring one generation at a time. It is easy to see the economic advantage of marrying into North Sea communities. Was there conflict and coercion? I am sure some existed; horror stories based on fact likely served the tabloid-like religious lessons of early monastic historians like Bede.
These new arrivals—the 74% of East Anglians who conquered the boulder-clay soils—were certainly prominent among my general ancestry. Their mixed descendants, the founders of an English identity, settled in their farmsteads, largely unmoved by the later Norman aristocracy, eventually becoming my high medieval ancestors.
