What is the history behind members from different families (LCN) marrying one another? How often did this happen? Were some bosses and families against such unions? Did these marriages provide any special economic and political moves for a family?

bill bonnanno and rosalie profaci. carlo gambino married his cousin who was a castellano. ignazio lupo and Salvatrice Terranova. its just very natural and common between crime families symbalizes a tighter bond and reinforces peace. not sure about the incest tho lol

Jimmy Burke's only daughter married Sonny Red's son Bruno

Soldier Eric Esposito from Philadelphia Mob married Gambino soldier Blaise Corozzo's grandaughter.

Tommy Gambino (Carlo's son) and Frances Lucchese who was the daughter of Tommy Lucchese.

Carlo Gambino's brother Paolo also married a Castellano. Paolo married his first cousin Caterina Castellano.

RFK when he was the Attorney General, in one memo "expressed an interest" on the subject of the Gambino's marrying their first cousins and the supposed "resulting imbeciles and morons that have come from such close intermarriage." lol!! Those were RFK's words, not mine.
