In the Godfather III, when Vincent is made Don of the Corleone Family, Michael tells him that he will now be known as Don Corleone.
But, if I am not mistaken, weren't Dons whose names were different then their Family names just called by their real names.
For example, after Carlo Gambino dies, and Castellano was made Don, he was called Don Castellano, not Don Gambino right?
Is this another Puzo thing, or was this a legitimate thing to do?


"I never wanted this for you. I work my whole life--I don't apologize--to take care of my family, and I refused to be a fool, dancing on the string held by all those bigshots. I don't apologize--that's my life--but I thought that, that when it was your time, that you would be the one to hold the string. Senator Corleone; Governor Corleone."
-Don Vito Corleone to his son, Michael
