Pretty much Uncle Frank's guys down south, right? After Costello, seems Marcello and Trafficante just focused on drugs and let their families die out to minimize legal risk.
What do you mean "let their families die out to minimize legal risk"?
It seems they both let their families die out for one reason or another. Marcello and Trafficante actually were quite active after Costello. I had that wrong. But it seems these men just didn't recruit much after the 1960s. Their names were linked to the Kennedy assassination. That might have had something to do with them laying low and letting their families die off, too. Could have been a request from other families.
