Strzok is polish – check his family history.
Pronounced should be strok (w/o the z) – don't out yourself as corsi audience by saying "strozack" or anything like that.
I can dig, and it's non of your business how many languages I speak, but it's more than three. Dig on Strzok's family history, instead of famefagging around here how professional you are.
yw. His family history goes back into Duluth, Minnesota, if I remember correctly. With polish names many (if not all) of them. Even found some pictures from the 19th century when I did the digging back then.
