Almost 300 years after the Romans left, scholars like Bede wrote about the Angles and the Saxons and their migrations to the British Isles. Scholars of many disciplines, including archaeology, history, linguists and genetics, have debated what his words might have described, and what the scale, the nature and the impact of human migration were at that time.
New genetic results now show that around 75% of the population in Eastern and Southern England was made up of migrant families whose ancestors must have originated from continental regions bordering the North Sea, including the Netherlands, Germany and Denmark.
With the new data, the team could also consider the impact of this historic migration today. Notably the present-day English derive only 40% of their DNA from these historic continental ancestors, whereas 20 to 40% of their genetic profile likely came from France or Belgium. Thisย genetic componentย can be seen in the archaeological individuals and in the graves with Frankish objects found in early Medieval graves, particularly in Kent.

“It remains unclear whether this additional ancestry related to Iron Age France is connected to a few punctuated migration events, such as the Norman conquest, or whether it was the result of centuries-long mobility across the English Channel,” says Stephan Schiffels, lead senior author of the study. “Future work, specifically targeting theย medieval periodย and later will reveal the nature of this additional genetic signal.”
