SNP Analysis
Group members will be positive for the following Single Nucleotide Polymorphisms (SNPs) from the broad I1 level to our terminal SNP: I-M253, I-DF29, I-L22, I-P109, I-S10891, I-FGC21732, I-FT2561, I-FGC21733 and I-FGC21765

I-L22
L22+ (aka S142+) is the main Nordic subclade. It is also very common in Britain, especially on the east coast where the Vikings settled most heavily, in the Low Countries and Normandy (also doubtlessly the heritage of the Danish Viking) as well as in Poland and Russia (Swedish Vikings). P109+ A mostly southern Scandinavian subclade, with a presence in all the regions settled by the Danish Vikings. It has been found sporadically in many parts of Europe, such as western Iberia, northern Italy, the Balkans, Lithuania and Russia. - from Haplogroup I1 (Y-DNA), Eupedia

I-P109
According to YFull's calculations Haplogroup I-P109 was formed about 3500 years ago and each of the major sub-branches (FGC16695, S10891, Y3664 and Y5621) were formed about 3400 years ago (as of July 17, 2021). The spread of the P109 marker may have begun in the Nordic Bronze Age. If YFull's calculations are correct (and based on the limited sample size)  it's possible that Norse settlement in the British Isles began at least as early as 1100 BC.  Several Bronze Age archaeological sites in the British Isles contain Baltic Amber (and other trade goods) that must have moved (along with traders and possible migrants) across the North Sea by boat.

I-FGC21732 (or I-Y13930)
The TMRCA for this haplogroup is about 2800 YBP placing it within the Nordic Bronze Age. I-FGC21732 spread from there (based on location of furthest known relative of those tested) to what is now Slovakia, Bulgaria, Croatia and Italy which may imply migration by the Goths in from 300-500 AD or from later Rus Vikings or Norman knights. Other locations include Ireland, Scotland, England and Normandy which may imply Viking age migrations. Neither precludes the possibility of an even earlier migration of people from southern Sweden during the Nordic Bronze Age or from anytime between about 700 BC to 850 AD (the TMRCA for FGC21765).

I-FGC21765
The SNP mutation known as FGC21765 / I-Y14225 formed (according to YFull) about 2300 YBP.  There are currently four branches of I-FGC21765: I-BY70495 (Lee); I-FGC21763 (Waugh); I-S7005 (Waugh); and I-BY160105 (Jackson) and the current TMRCA (without the Viking sample) is 700 ybp (or around 1300 AD).
