I thought that Zaza was a member of the Corleone family.
In the Godfather III, they was present at the Commission meeting:

Tattaglia Family: Don Altobello
Cuneo Family: Leo Cuneo
Corleone family: Michael (I thought that Zaza was the boss because Mike is retired)
Barzini family: ?
Stracci Family: ?

Frank Romano, Matty Parisi, Albert Volpe... are dons that were in the meeting

So, Zaza, Which is his Family?
Bye
