Anyone who’s read even a bit about the history of the Vikings knows that their DNA is likely to be found in people living in the British Isles today. New research shows that the Irish definitely have their fair share of Viking heritage–in fact, the Irish are more genetically diverse than most people may assume.

The Irish have Viking and Norman ancestry in similar proportions to the English. A comprehensive DNA map of the Irish has for the first time revealed lasting contributions from British, Scandinavian, and French invasions.

“By comparing 1,000 Irish genomes with over 6,000 genomes from Britain and mainland Europe, genetic clusters within the west of Ireland, in particular, were discovered for the first time, leading the researchers to investigate if invasions from the Vikings and Normans to the east may have influenced genetics in that part of the country,” according to Irish Central.

Because of extensive Irish immigration to the United States and other countries, these findings have ramifications. There are 80 million people in the world who claim Irish heritage. “This subtle genetic structure within such a small country has implications for medical genetic association…
