I guess that's up for debate. From what I understand it is generally believed that the Morellos founded the outfit that eventually became known as the Genovese family. Masseria took over their outfit after Morello and his brothers were out of ther picture. It is true that the family splintered in two different groups, the Reina group and the Masseria group. But these two groups would not have existed were it not for the Morellos.
