Here's a simple rule of thumb:

If an Eastern European R1b1b2 haplotype has fairly close matches in the much
more heavily sampled Western countries, it can probably be attributed to
modern (or late medieval) eastward immigration. Otherwise, the haplotype
probably predates such immigration.

In my project, I've encountered a few R1b1b2 and I1 cases that look like the
result of recent immigration. Most do not, for the very simple reason that
such immigrants--or, since the 18th-century occupation of Poland,
"colonists"--generally retained their foreign culture. Their descendants do
not consider themselves Polish (or Ukrainian etc.) and do not join my

Ancient or early medieval immigration is, of course, harder to argue in
either direction. Does much Polish R1b1b2 descend from Goths or other East
Germanics? It's difficult to say, especially since we do not have
identifiable modern correspondents with which to compare.
