Clooney's ancestry includes Irish, German, English and more distant Scottish and Dutch roots.
George Clooney was born on May 6, 1961, in Lexington, Kentucky, United States, into a well-known family of media and entertainment personalities. He is a son of Nina Bruce (Warren) Clooney, a former beauty pageant queen and city councilwoman, and Nick Clooney, a former anchorman, as well as a game show and American Movie Classics host.
George's maternal great-great-great-great-grandmother, Mary Ann Sparrow, was the half-sister of Nancy Lincoln, mother of President Abraham Lincoln. Cabaret singer and actress Rosemary Clooney was his aunt. Betty Clooney, an American singer and TV presenter, was also George's aunt.
It's also worth mentioning, that George's patrilineal line traces back to Nicholas Clooney (of County Kilkenny) and Bridget Byron, his great-great-grandparents, who emigrated to the United States from Ireland.
Clooney has an older sister, Adelia (commonly known as Ada). His cousins include actors Miguel Ferrer, Rafael Ferrer and Gabriel Ferrer.
