Here's a good one that I forgot.

Pasquale "Patty Ryan" Eboli and his nephew Louis "Mooch" Eboli (Son of Thomas "Tommy Ryan" Eboli)

Pasquale Eboli was a Genovese captain and close with his brother; Thomas Eboli who was Acting Boss (Underboss or Front/Not sure during that time in the early 70's).

Louis Eboli was a Chicago-based made guy and the son of Thomas Eboli.

So; Pasquale and Louis are Uncle and Nephew.
