He is mostly from Masovia (around Płock) based on his recent genealogy thread here:

And I tested (autosomal + Y-DNA) my maternal grandpa's brother with this surname.
He turned out to be autosomally more eastern-shifted, and Y-DNA is R1a. Surprising?
Here his coordinates if you want to check (there is some southern admixture as well):

Check him with your model, I'm curious (probably will be high amount of Greco-Roman).
