The Masseria crime family and the Morello/Terranova one were one and the same. Masseria came after Giuseppe Morello. For various reasons Morello could not become a boss again after he came out of prison, so Masseria succeeded him while Morello advised him. Morello was his underboss, but in many ways "the power behind the throne." Salvatore Pollaccia was Masseria's consigliere. An accurate list of capos is impossible right now because we don't have that information. Luciano, Capone and Ciro Terranova were caporegimes, maybe Vito Genovese and Frank Costello were also. Frank Yale was one.
