Interesting info regarding the Philly Mob - they actually started out as part of the Castellammarese Clan in Williamsburg up until 1931, then split off as their own family. John "Nazzone" Avena took over after Maranzano's death in 1931. I remember reading in Joe Bonanno's book that he insulted Salvatore Sabella's brother Michele, Michele asked Sal to come over to New York while Joe called on Steve Magaddino for support, but Maranzano took Bonanno under his wing.

Some questions to ask though:
1. Was Sabella asked by Bonanno to step down or did he retire voluntarily?
2. Who was Angelo Bruno's sponsor and when was he inducted into the Philly Mob?
3. It is true that Salvatore Sabella's related to Mike "Mimi" Sabella (one of the Bonanno mobsters involved in the Donnie Brasco scandal and a loyal henchman of Carmine Galante), but how?
