in the book 'Relazioni mafiose. La mafia ai tempi del fascismo' written by Vittorio Coco and published in 2013, there is an important document
in 1937 (a year before the declarations of another turncoat, Melchiorre Allegra) the turncoat Salvatore Anello (nephew of Tommaso Natale boss Rosario Napoli), questioned by the fascist police, described the mafia structure and the ritual of initiation. He said the organization was formed by several families formed by about 20 members, led by a 'rappresentante' or 'presidente' and divided into 'decine' led by 'capidecina' (the turncoat Salvatore D'Amico said almost the same things in 1878), he also said at that time the mafia was active abroad, especially in the United States, France and Tunisia. But the most important thing he said was that the 'presidenti' answered to a 'general president' and that there was a 'commission' who ruled the organization; he also said Ernesto Marasà, boss of Boccadifalco, wanted to become the boss of bosses
if it is true it would be the proof that the 'commission' existed before the 1950s, period in which many believed it had been created and copied by the American mafia
