There was an informant in Chicago in the early 1960s who said he was an old-timer who was accepted into the Outfit in the early days because he had an Italian last name and he looked Italian. The details were sketchy and the document was heavily redacted(can't find it at the moment) but he said he had moved to Chicago from the East Coast. My guess would be that he was really an Italian Jew. He said if word got out, he'd be in danger. Could be BS who knows.
