Yes, guys testify or flip and then after the fact say that dual membership is prohibited, yet we have plenty examples that contradict said prohibition. Salvatore "Toto" Catalano for one, was a Bonanno made man, and at one point acting boss, but he was also made in Sicily. Some on The Black Hand, tend to deny this, but every literary source that I've come across in regards to Catalano state that he was made in Sicily. There's also Three Fingers Coppola, a made member of the Detroit Partnership, part of the Partinico Faction, there are sources which claim that after setting up his heroin network in Sicily, he was an active member and at one point led the Partinico Family, in Sicily.

There's John Stanfa, whom was a made man in Sicily and a made man in the Philadelphia mob.


And again, the Cherry Hill Gambinos are prime examples of the contradiction.
