Notes on Y-Chromosome Haplogroup I   See:  Haplogroup I Subclade
Analysis by Ken Nordtvedt  The Haplogroup I, I1, and I1a
lineages are nearly completely restricted to northwestern
Europe. These would most likely have been common within Viking
populations. One lineage of this group extends down into central
Europe. Source: FamilyTreeDNA:  If DYS19 = 14 and DYS392 = 11
then you are likely haplogroup I1a Source Ken Nordtvedt  If I1a
with ancestry in the British Isles and 22 at DYS390 then more
likely Saxon origin. If I1a and 23 at DYS390 then more likely
Norse origin Source Ken Nordtvedt  The ancestors of Haplogroup I
(defined by the P19 and M170 genetic markers) arrived from the
Middle East 20,000 to 25,000 years ago and are associated with
the Gravettian culture. Gravettian is the second subdivision of
the Upper Paleolithic technological phase in western Europe
(from 27,000 to 21,000 years ago). Haplogroup I is most frequent
in central Eastern Europe and also occurs in Basques and
Sardinians.  Haplogroup "I" i
