Banks families and other closely related
persons within Haplogroup I1a2a
common ancestor likely in northern Europe in pre-Christian era
Haplogroup I1a2a persons are today especially concentrated in Scandinavia though found in
significant numbers all over northern Europe. The specific mutation associated with I1a2a is P109.
The specific marker values seen here on this page are not typical of those from the Viking areas of
northern Scandinavia, but rather are common in southernScandinavia and northern Germany.

Eur J Hum Genet. 2006 Dec;14(12):1288-94. Epub 2006 Sep 6. The scale and nature of Viking settlement in Ireland from Y-chromosome
admixture analysis.McEvoy B, Brady C, Moore LT, Bradley DG. Smurfit Institute of Genetics, Trinity College, Dublin 2, Ireland.
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.
