Abstract

The Vikings (or Norse) played a prominent role in Irish history but,
despite this, their genetic legacy in Ireland, which may provide
insights into the nature and scale of their immigration, is largely
unexplored. Irish surnames, some of which are thought to have Norse
roots, are paternally inherited in a similar manner to Y-chromosomes.
The correspondence of Scandinavian patrilineal ancestry in a cohort of
Irish men bearing surnames of putative Norse origin was examined using
both slow mutating unique event polymorphisms and relatively rapidly
changing short tandem repeat Y-chromosome markers. Irish and
Scandinavian admixture proportions were explored for both systems
using six different admixture estimators, allowing a parallel
investigation of the impact of method and marker type in Y-chromosome
admixture analysis. Admixture proportion estimates in the putative
Norse surname group were highly consistent and detected little trace
of Scandinavian ancestry. In addition, there is scant evidence of
Scandinavian Y-chromosome introgression in a general Irish population
sample. Although conclusions are largely dependent on the accurate
identification of Norse surnames, the findings are consistent with a
relatively small number of Norse settlers (and descendents) migrating
to Ireland during the Viking period (ca. AD 800–1200) suggesting that
Norse colonial settlements might have been largely composed of
indigenous Irish. This observation adds to previous genetic studies
that point to a flexible Viking settlement approach across North
Atlantic Europe.
