Since Unione Sicilone had non Sicilians,even Frankie Uale,a Calabrian as its head,was it a case like the mafia being Sicilian but eventually admitting other Italians to its membership

Or did the word Sicilione refer to the fact that Mainland Southern Italy and Sicily were at times all called the Kingdom of Sicily and at other times including right before Italy's Unification it was called the Kingdom of the Two Sicilies?
