I've got a bit of a request. Can someone take a look at the Kaszub I-M253* and maybe try and work out its source?
Rumour has it, they're partly of Gothic origin. Actually, it was claimed they were entirely of Gothic origin, but we now know they're pretty much a northern Polish population in terms of genetics.
However, where does that I-M253* derive from? It's more numerous in Kaszubs than in Germans from Macklenburg, which is interesting.
The STRs are in the Excel sheet here...http://www.nature.com/ejhg/journal/vaop/ncurrent/suppinfo/ejhg2012190s1.html?url=/ejhg/journal/vaop/ncurrent/abs/ejhg2012190a.html
