>Most of the Anglo-Saxons buried at Updown traced their ancestry to Northern Europe, but a girl buried around 650 C.E. had roots much farther afield, researchers report in a paper published today in the journal Antiquity. “Her paternal grandfather was 100% West African,” says Stephan Schiffels, a geneticist at the Max Planck Institute for Evolutionary Anthropology who co-authored the new research. The girl’s grandfather would have been a match for people living in what is Nigeria today.

>In a parallel paper, also published in Antiquity, a team including some of the same authors revealed that another Anglo-Saxon individual—a young man buried around the same time in a rural cemetery in nearby Dorset called Worth Matravers—carried West African ancestry, likely inherited from a paternal grandfather.
