From what I have gathered is that basically after Masseria and Maranzano, and even Rothstein were killed. Everyone, joined CN in 1931, with Original 5 Families of NYC. Prior it was the same groups out of Southern Italy (CN, Ndragheta, Camorra) either at war or working together in North America. I even think Lansky, Costello, and Tommy Lucchese were 5 point when they were coming up.
In Sicily, women are more dangerous than the shotgun.
