The Sicilians for sure. I always assumed it was the Castellammare del Golfo faction that had the most impact. They fought a whole mob war here over it.
They lost though, which was probably why Bonanno's old Maranzano family was never really in the same league as the Luciano/Genovese, Luccheses and Gambinos in their prime.
Palermo seems to have the most influence in the U.S. among Sicilian clans here, through the Gambino family.
I would say the Americanized faction of the mob is still in charge however I'm interested in the Bellomo connections to Corleone.
