Dill was born in Bermuda. Her mother was Ruth Rapalje (née Neilson), with roots in New Jersey, and her father, Lieutenant-Colonel Thomas Melville Dill (also the name of her great-grandfather, a mariner), was a former Attorney General of Bermuda, and former Commanding Officer of the Bermuda Militia Artillery. Her father was from a prominent Bermudian family, present on the island since the very early 17th century. Her ancestry includes English, Scottish, and Dutch. Her brother Bayard was a prominent lawyer and politician. Her sister Ruth was married to John Seward Johnson I, heir to the Johnson & Johnson fortune. Dill was brought up in the Church of England.
Dill was married to Kirk Douglas, with whom she had studied acting before World War II. During the war, Douglas was serving in the U.S. Navy when he saw the May 3, 1943, issue of Life magazine, which featured a photograph of Dill on the cover. He showed the cover to his shipmates and said that he would marry her. The two were married on November 2, 1943. They had two sons, Michael and Joel, before divorcing in 1951.
