Jack Nicholson was born in St. Vincent's Hospital in New York City, the son of a showgirl, June Frances Nicholson (stage name June Nilson).
June had married Italian American showman Donald Furcillo (stage name Donald Rose) six months earlier in Elkton, Maryland, on October 16, 1936.Elkton was a town known for its "quickie" marriages. Furcillo, however, was already married, and, although he offered to take care of the child, June's mother Ethel insisted that she bring up the baby, partly so that June could pursue her dancing career. Although Donald Furcillo claimed to be Nicholson's father and to have committed bigamy by marrying June, biographer Patrick McGilligan asserted in
Jack's Life that Latvian-born Eddie King (originally Edgar A. Kirschfeld), June's manager, may be the father, and other sources have suggested that June Nicholson was unsure of who the father was. Nicholson's mother was of Irish, English, and Dutch descent, though he and his family self-identified as Irish.
