My great-grandfather's name was Rudolph (maybe rudolf) hoffman, and apparently was a member of the Chicago Outfit. I heard this from my mother. I always figured we were german, but looking back to it, my grandfather had black hair, dark olive skin, dark circles under eyes. My mother also has these qualities with fairer skin, and I also have a similar complexion to her. My mother said he didn't just work for the outfit, he was IN the outfit itself. My question is, does this insure my great-grandfather was 100 percent Italian, if not, do you guys know have any information on that last name affiliated with the outfit?

Thanks for the time,
Jon

Edit: I'll post a picture of my grandfather tomorrow so you guys can see why I am pretty sure he is Italian.
