What is the Italian translation of 'the godfather'?

There is Don Vito Corleone who is the Godfather. He has 3 sons Sonny, Fredo and Michael. He has a daughter played by Talia Shire who does not really count and there is Tom Hagon who is Vito's right hand man (seen sitting down on the couch, closed to the edge of your screen, in the opening scene) There are other supporting characters like Aldo Tripanni, Hymon Roth and other guys
