He may have earned his first Oscar as the young Vito Corleone in The Godfather: Part II, but Robert De Niro’s real father is of both Italian and Irish descent. His father, Robert De Niro Sr., was the son of Dennis O’Reilly and Mary Burns, and the famous Robert De Niro Jr. spent some time visiting the land of his forefathers as a teenager in 1962. “I hitchhiked from Dublin to Galway and took the ferry to the Aran Islands, then I went down through the south,” he told The Independent. “People gave me blankets for sleeping outside and I had breakfast with them in the morning. They were very friendly." Timely enough, up next for the current Limitless star is Martin Scorsese’s highly anticipated project The Irishman.
