there was a question in this questionaire i had to fill out at school one time for a scholarship and the question started where in italy did you ancestors come from? that's when i realized that i am not really italian b/c i have no idea. maybe i should just walk around italy until i find people that look like me and then i'll know.
there should be some record of where your grandparents came from when they immigrated. or you can look up your surname and see what region it is from. we still have family over there we are in touch with, so its not much of a mystery.
