I tried to write the succession of provincial representatives of all the provinces represented in the mafia commission, but the sources I found state incomplete information, many dates are missing and there is very little information about the underbosses and consiglieri. Also, there is much confusion about the Catania province, as I don't understand who was Santapaola's successor as representative of the province. Different sources I found on internet and in books list his son Vincenzo, Calogero Conti and Eugenio Galea, but don't state the chronological order and the dates. Maybe somebody could provide information so I can fill the missing parts?
