Ok. Last round of picks, Rocco Pellegrino, Rosario Mogavero, Eugene Catena, Peter DeFeo,and Generoso Del Ducca. Of course guys get transferred between crew all the time before they become capos, but I am confident it is one of the above names, DeFeo and Pellegrino had long runs, Del Ducca only a few years before he died, Catena and Mogavero had decent runs.
GV, the mafioso in question was capo Vincenzo (Jimmy Angellina) Angelino.
In fact, we just released his biography on our website. I also posted a link to it here in a separate thread.
