The godfather was born Vito Andolini, in the town of Corleone in Sicily. In 1901 his father was murdered for an insult to the local Mafia chieftain. His older brother Paolo swore revenge and disappeared into the hills, leaving Vito, the only male heir, to stand with his mother at the funeral. He was nine years old.
