Any instances of A capo and his entire crew switching families? None to my knowledge. You had many associates that would later become soldiers that switched families over beefs, you had made guys in the higher levels like Nicky Bianco going back and forth between New England and the Colombo Family and back to New England. You had Johnny Roselli who was a high up Chicago guy who went over to the LA Family for a time and then back to Chicago before he was whacked. To my knowledge no Capo switched himself and his entire crew to another family. Closest to that happening was associate Kid Blast Gallo and Punchy Illiano took portions of their crew to the Genovese Family and where made in the late 70s after that. They were unmade in any family, their crew were at odds with other members of their crew which one Mooney Cutrone was made in the Colombo Family. They had their own little Civil War, Kid Blast and Punchy went with the Genovese, Mooney and the other guys went with the Colombos. After this Mooney still tried to take out the Punchy/Kid Blast faction, Mooney was in the wrong, was killed along with another of his faction. Kid Blast and Punchy were made soldiers in the Genovese, had their crew which was under their protection and the Genovese banner like Preston Geritano. other members of their crew like associate Bobby Boriello chose to go with another family (Gambino) during this unrest within the original Gallo crew. Gallo and Illiano were eventually made Co-Capos of this crew.
