Thanks for your input guys, very interesting.

American Cosa Nostra originated from Sicilian origins but now has "expanded" to include members from all regions of Italy as long as their mother and father have Italian last names now.

Whats intriguing to me about that is: That is not a very discerning requirement for membership in the present day.

That means that a redneck from the town I live in in that has an Italian last named Mom and Dad can go to New York or Chicago and possibly become a made guy or even a boss. How crazy would that be: some dude with a mullet from a trailer park in Bellevue Illinois becomes boss of the Bonannos because he had an Italian American mom and dad?
