Genealogy / Americans of Polish descent. How many of us are on Polish forums? [216]

I just found this forum.
I'm looking into Polish Citizenship by descent, since my father was from Poland.
Actually from what I heard he was an officer in the Polish Military.
However he died when I was 3 years old and I don't know much about him.
I have some paperwork of his like a Naturalization paperwork when he became a US Citizen.
Looking into getting more information like where he was born so that I can see if I can qualify for Poland citizenship.
May also be interested in retiring in Poland and visiting there as well.

History / Is there a list of those in the Polish Army during WWII? [193]

I'm just starting to research my ancestry. My father died when I was 3 years old so I don't really know him. I've heard over the years he was in officer fought in Africa, Italy and may have been in a concentration camp. I've recently been told that I can become a citizen of Poland etc from someone I just met. Anyways, his last name was Derdau as is mine. I'm hoping to find out more and learn a little about my heritage. Any pointers and assistance would be very helpful and appreciated. I live in the United States and may one day hope to visit Poland. Thank You.
