Don Vito Corleone (Marlon Brando) The Godfather - head of the 'family business' which is an Italian mob organization he forged migrating to the United States. He raises his children under strict guidlines and mafia rules. One of my father's inspirations for quotes and guidelines: "Never tell anyone outside the Family what you are thinking."
Clemenza as portrayed by Bruno Kirby, journeyman actor who in my opinion not as appreciated as he should have been. "When Harry Met Sally," "City Slickers," "Donnie Brasco," "Hoffa," the list goes on.
Apollonia Corleone married Mike, a friend of her brother Sonny, at a lavish old-style Sicilian ceremony in 1945. They agreed to the ceremony due to her father's displeasure in her choice of groom (he was not only a hoodlum, but half-northern Italian).
