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.

After Morellos convicton D`Aquila took his place as supreme authority over the fraternity. If I remember correctly Morello was sentenced to death at a fraternity meeting although later revoked, which must have been the reason why he was not allowed to assume his old position.
At the time he came out of prison his halfbrothers, Ciro and Vincenzo, were leading the Morello-Terranova Clan. One of his allies at that time was Umberto Valenti(East Village).
As of Masseria, his connection to Morello could have been a Man named Lima with whom he was arrested in 1907. Note Morellos sister Marie married a man named Giaoacchino Lima.
Basically, Masseria had luck. As Prohibiton started he was the one who profited more than others because his territory happened to be called the Curb Exchange (Kenmare Street, Little Italy).
In 1921 Masserias power was second only to D´Aquila, which is why Morello probably sided with his one time underling.
