In Dorset, England, DNA From 50+ Iron Age Burials Shows Most Traced Their Maternal Line to One Woman

A Nature study of more than 50 ancient genomes from Iron Age burial grounds in Dorset, southern England, found that most members of one kin group traced their maternal line to a single woman who lived centuries earlier. Paternal-line relationships were almost absent. The authors infer that husbands moved to live with their wives’ communities after marriage, a pattern called matrilocality. Lara Cassidy of Trinity College Dublin led the work, with Dan Bradley, Miles Russell of Bournemouth University and Martin Smith.

The Dorset burials

The graves come from burial grounds used before and after the Roman Conquest of AD 43. The key site lies near the village of Winterborne Kingston, nicknamed “Duropolis,” which Bournemouth University has excavated since 2009. The community links to the Durotriges, the name the Romans gave them. Dorset is unusual for well-preserved Iron Age burials because of local burial customs. Earlier work had already shown that the richly furnished Durotrigan burials were women’s. A young woman at Langton Herring lay with a mirror, jewellery and a Roman coin amulet showing a female charioteer who represents Victory.

What the genomes suggest

The authors suggest that land may have passed down the female line, and they describe it as the first documentation of such a system in European prehistory. The same pattern appeared across other Iron Age cemeteries in Britain, including one in Yorkshire, where one dominant matriline was established before 400 BCE. Members of distant branches of the family married each other, but close inbreeding was avoided. The study also found Iron Age migration into coastal southern England that earlier genetic studies had missed. Russell said maternal ancestry may have been the main shaper of group identities.

What remains uncertain

The Dorset result rests on one large site, and the other cemeteries had much smaller samples. Social conclusions such as female political empowerment are inferences from genetic and burial data. Roman and Greek writers are not always reliable, and Russell suggests the Romans may have exaggerated the freedoms of British women.
