There are some sources who've listed Pittsburgh's/Rochester's Costenze (Stanley) Valenti as the boss of that Family. But, in reality, his older brother Frank Valenti was the true boss of this crew.

I think, at the time, some law enforcement agencies (the feds included) took for granted that Stanley was the boss because he was the one married to old-time La Rocca capodecina Antonio Ripepi's daughter. Ripepi was a very powerful Calabrian based power who later rose to become a Cosa Nostra capo.

But, truth be told, Stanley was a nonentity, compared to Frank. There was no comparison whatsoever. Frank was the hoodlum!
