During his tenure as boss, who was Vito Genovese's closest ally in the other four NYC/NJ borgatas?

What bosses? And what other top players of the Bonanno, Gambino, Colombo, Lucchese, and DeCavalcante crews?

Tommy Lucchese had Carlo Gambino
Joe Profaci had Joe Bonanno
Nicky Delmore had Vito Genovese
Frank Costello had Albert Anastasia

But who did Vito have a top backup in another family?

Food for thought
