just wanted an answer
With the limited information you have provided, I don't think you will get anything except for speculation.
Perhaps if you gave us more information we could be of more assistance.
When did your Grandfather move to the U.S.? this may be a clue as to why he said he changed his identity to Polish, to be more American friendly. Also was he under strong medication? as it is possible that he was not fully conscience of what he was saying.
they messed up the spelling of our last name.
Also tell us your last name and we might know something about that too.
not really just wanted an answer...no smart asses
It's the internet, don't worry.
