I'm deferring to Franzes's point of view. In other words, the families relevant to him. Franzese was a New York guy and he was also into high end rackets, so you have to work backward from the families that he would consider relevant when he was active. I don't see him needing New England for much.

"...the successful annihilation of organized crime's subculture in America would rock the 'legitimate' world's foundation, which would ultimately force fundamental social changes and redistributions of wealth and power in this country. Meyer Lansky's dream was to bond the two worlds together so that one could not survive without the other." - Dan E. Moldea
