According to the FamilyTreeDNA Rurikid Dynasty DNA Project, Rurik appears to have belonged to Y-DNA haplogroup N1c1, based on testing of his modern male line descendants.
O’Rourke family (R1b-L21 y-dna)
Further genetic studies seem to indicate the existence of two major haplogroups among modern Rurikids: the descendants of Vladimir II Monomakh (Monomakhoviches) and some others are of N1c1 group (130 people or 68%), while the descendants of a junior prince from the branch of Oleg I of Chernigov (Olgoviches) and some others (total 45 peoples or 24%) are of R1a and R1b haplogroups (typical for Slavic, Germanic, Nordic, Finnish, Baltic and Celtic peoples).
