My family is pretty easy to figure out, we're 100% Polish!
Father's Family: The countryside around Torun, Poland
Mother's Family: Aleksandrow Kujawski, Poland
I am a 3rd generation American. Though my maternal-grandfather was born in the the US, his mom missed the homeland and moved everyone back to Poland. Thus he grew up in Poland. At the age of 19, he came back to the US just at the start of WWII. In September, I had the awesome opportunity to visit my great-uncle and cousins in Aleksandrow Kujawski. I got to see where my grandfather went to school, where he used to work, and the plot of land where his house used to be. Cool!
Edited to add: I visited my father's family too! I didn't mean to imply that I left them out or something!
