Hi dominic_calabrese, you asked about how men like Gaetano Lucchese and Francesco Castiglia (Frank Costello) were able to cross over into borgatas different from where their families originated in Italy.

I think in Tommy Lucchese's case, it had to do with him being a young member of the 107ht street mob as a youngster, and then graduating into the Reina mafia family as an adult. Tommy basically built his street cred being a young hoodlum in a gang that carried on in Corleonesi territory of Manhattan. The 107th street mob was likely a junior mafia that the Morellos and/or Reinas recuited from.
