The Viking Y-DNA Project currently exhibits a slight bias towards haplogroup I1 given the geographical range of the vikings roughly corresponding to the georgraphical core of I1.  Make no mistake, not all I1 were vikings and not all vikings were I1. Other haplogroups as (such as G2, N, R1a, and R1b), that form part of "the Viking thumbprint". We would therefore like to encourage everyone with a clear paternal origin in the Viking areas of the British Isles (Incl. Ireland), Normandy, Norway, Iceland, Sweden, the Baltic, Russia, Ukraine, Poland, Germany, Netherlands, and Denmark, to join the Viking Y-DNA Project.
