Jews, huh? I was also thinking of that. Maybe a character could be part of some Ashkenazi organization that originated from Poland/East Europe. Greeks and Irish also had their own organized groups so maybe a character associated with one of those groups could also be a good idea.

Yeah, there were some really infamous New York City Jewish gangsters. Meyer Lansky kept on steaming for a good long time. Love the story about Lansky and associates stepping out of the usual role to make a meeting of the German-American Bund piss their lederhosen in the 1930's. That's some hilarious stuff.
