The Sorenson pedigrees for the Western I1b were mainly in England, spread
around (Northhampton, Lankashire, Worcester, Nottingham), one Scot, one
Ireland with English name; 2 North Germany, 1 Dane from Schleswig-Holstein,
and 1 Prussian, 1 Norwegian. Capelli shows a cluster of about 10 Western
I1b spread around British Isles plus 3 from Anglo-Saxony/Denmark, and 1 from
Norway. Rootsi et al paper shows a handful from eastern and southeastern
Europe (identified by the DYS388 = 15); they represent a very small
percentage of the entire I1b Rootsi
population, but are SNP-tested P37positive, M26negative or I1bxI1b2.
> They have very low variances on the 24 markers when compared to my
root I1a population, showing only 43 percent of the variance of my I1a
standard. Based on the 10,000 year estimated age for the standard, this
yields a 4300 year age for the Western I1b.
> This I1b variety's very young age requires another careful look at its
geographical distribution in northwest Europe which is rather different than
that of the normal I1b of eastern and southeastern Europe.
