The Corleone Family is the center of the events of The Godfather Trilogy; however, there are so many members it can get hard to follow at some point.
Summary SCREENRANT VIDEO OF THE DAY SCROLL TO CONTINUE WITH CONTENT Considering that The Godfather follows over 80 years of family history, relationships can get tricky at some points in the convoluted family tree. In addition to this, being that this is a mafia story, the existence of two types of families can also make things a bit confusing. On the one hand, there are the blood relatives; on the other hand, there are the members of the mob family.
19 Federico "Fredo" Corleone Federico "Fredo" Corleone is Vito Corleone’s second son. He is also brilliantly portrayed by Jonh Cazale. Although Fredo is a key character in the first two films, he only appears during a flashback in the last movie. He is the incompetent son who is usually looked after by his brothers. Once Michael takes control of the family, he names Fredo underboss. Of course, this is just a title to make him feel useful.
15 Sandra Corleone Sandra Corleone is Santino “Sonny” Corleone’s wife. She is not that important a character, but she is the mother of Sonny’s four kids, two boys and two girls. In addition to this, Sonny has one illegitimate son with Lucy Mancini, which becomes relevant in The Godfather III. Obviously, Sandra did not raise Sonny’s illegitimate son.
11 Johnny Fontane Johnny Fontane is not blood-related as he is Vito Corleone’s godson. Johnny is a secondary character in the first Godfather movie and appears in a scene during The Godfather III, both times played by Al Martino. Johnny Fontane is a singer based on Frank Sinatra who triggers one of the Godfather’s most iconic scenes, when Vito Corleone puts a horse head inside a Hollywood producer's bed to get his godson a role in a movie.
