Anglo-Saxons were only 24% English, study reveals
Anglo-Saxons were only 24 per cent English, a new study has revealed.
Researchers from Max Planck Institute for Evolutionary Anthropology carried out a genetic study to understand the scale, nature, and impact of human migration during the Medieval period.
Their findings suggest that mass migration into the UK from Germany, The Netherlands and Denmark during this time may have increased European ancestry up to 76 per cent.

Their findings suggest that mass migration into the UK from Germany, The Netherlands and Denmark during this time may have increased European ancestry by as much as 76 per cent
In the study, the team analysed archaeological data and DNA from 460 medieval people dating back between 200 and 1300 CE, including 278 people from England.
Their analysis revealed that 76 per cent of the population in Eastern and Southern England was made up of migrant families, whose ancestors originated in the Netherlands, Germany or Denmark.
According to the researchers, these families interbred with the existing English population – although this varied between regions and communities.
Joscha Gretzinger, lead author of the study, said: ‘With 278 ancient genomes from England and hundreds more from Europe, we now gained really fascinating insights into population-scale and individual histories during post-Roman times.
‘Not only do we now have an idea of the scale of migration, but also how it played out in communities and families.’
The researchers compared the data from the medieval individuals to genetic data from more than 4,000 ancient and 10,000 present-day Europeans.
This revealed subtle genetic differences between closely related groups.
In one case, an Anglo-Saxon cemetery in Buckland near Dover enabled the international team to reconstruct a family tree across at least four generations.
Archaeologists excavate a complicated triple burial while working at Oakington Cambridgeshire. These three women were not related to each other, and each had a different proportion of WBI (Western Britain and Ireland) and CNE (Continental North European) ancestry
The study also showed women of immigrant origin were buried with artifacts such as brooches and beads more often than local counterparts
They identified the point in time when migrants and locals intermarried. This family showed a large degree of interaction between the two gene pools.
Overall, the researchers witnessed burials of prominent status across cemeteries of both local and migrant origin.
The study also showed women of immigrant origin were buried with artefacts such as brooches and beads more often than local counterparts.
Archaeologists excavate grave 112 at Oakington Cambridgeshire, it contained an adult male buried with a knife. He had 99.99% CNE ancestory
On the other hand, men with weapons were just as likely to be native or of immigrant ancestry.
These differences were locally mediated with prominent burials or wealthy graves seen across the range of origins.
For example, a woman buried with a complete cow in Cambridgeshire was genetically mixed, with majority local ancestry.
Co-lead author Professor Duncan Sayer, of the University of Central Lancashire, said: ‘We see considerable variation in how this migration affected communities.
‘In some places, we see clear signs of active integration between locals and immigrants, as in the case of Buckland near Dover, or Oakington in Cambridgeshire.
‘Yet in other cases, like Apple Down in West Sussex, we see people with immigrant and local ancestry were buried separately in the cemetery. Perhaps this is evidence of some degree of social separation at this site.’
Present-day English people derive only 40 per cent of their DNA from these historic continental ancestors, while between 20 and 40 per cent likely came from France or Belgium.
This genetic component can be seen in the archaeological individuals and in the graves with Frankish objects found in early Medieval graves, particularly in Kent.
Lead senior author Dr Stephan Schiffels, also of the Max Planck Institute, concluded: ‘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.
‘Future work, specifically targeting the medieval period and later will reveal the nature of this additional genetic signal.’
