Stolarek et al: Genetic history of East-Central Europe...

[Radko]

There are obviously a lot of immigrants in Medieval Poland.

These can also be the Restgermanen, not necessarily recent immigrants.

I find it hard to believe that Goths and other Restgermanen survived in Poland another 500-600 years after the collapse of Wielbark and Przeworsk cultures. Recent immigration is much more probable.

I'm not saying that they survived, but that they were their genetic descendants.

They could be already Slavicized linguistically but still very Germanic autosomally.

How would you explain "young" Y-DNA lines such as R-S22194 (TMRCA 517 CE according to FTDNA, shared mostly with modern Western Germans and Theo der Pfeifenraucher) in Santok other than Medieval German migrations?
