Sure he did. Looking way back on his family tree, there are some Germans, some Canadian Indians, some Irish (where I get my last name from), and a bunch of other things. I don't know any of my ancestors from any of those countries and nobody on his side of the family have any sense of identity with those cultures. Where as on my mothers side of the family, I am only the second generation to be born in the United States and my entire upbringing was heavily influenced by Greek culture. When I see these family members, I am seeing people that actually moved to the United States from the axis-occupied Greek Island of Ikaria following the end of WWII. My own grandmother whom I lived with for a good portion of my childhood was one of these people. This isn't to say that my ancestry on my fathers side of the family isn't worth studying and being proud of, but I naturally have a greater sense of identity with the Greek heritage that I have known my whole life.
