It was Nick Sr that married into it, was Nick's wife not a daughter of a very powerful man back in Sicily?
She was the daughter of Agrigento Province Don, Atonio Manno. Nick Sr's, I mean. I think Vito's wife was likewise Sicilian, but I'm not entirely sure about that.
Not to split hairs, but Antonio was capo of Cattolica Eraclea, not the Godfather of entire Agrigento province.
