Something else maybe noteworthy regarding the southern families in particular, there were no Irish mobs there to inherit rackets from like there were in the east coast and midwest cities (and even west coast, for that matter). They at least shared or took control from protestant good old boys, which couldn't have been easy. This is why I think it's important to cite the political connections of the southern mobs. Trafficante, Marcello, Civello in Dallas (who I believe was pretty much with Marcello). They must have had solid political connections.
