Im assuming rustelli and marangello were both sicilians since joe bonanno was only for inducting them into his family. His whole book was about that. Theres pics of the zips with marangello so its safe ti say he was fluent in there dialect. Nick was a old guy but he was around since forever and probaly had relationships with all the family. He kinda had a social club like fat tonys. Open a few hours a day for business only. Not great a nyc geography but if his place was on hester street that what around the corner from the ravenite and probaly 20 other clubs back then
