Kathleen Agnes Kennedy

Biography
When President Franklin D. Rossevelt appointed Joseph Patrick Kennedy ambassador to the United Kingdom, his daughter Kathleen spent a year and a half living in London. She was educated in London at Queens College. Beautiful and spirited, she was named the "most exciting debutante of 1938". In 1943, she returned to England to work in a centre for servicemen set up by the Red Cross. Despite the opposition of her intensely Catholic mother, Rose Fitzgerald Kennedy, Kathleen Kennedy, known to friends as Kick, married Marquess of Harrington, an Angelican and the eldest son and heir of the 10th Duke of Devonshire on May 6, 1944. Other than her eldest brother Joseph Patrick Kennedy, Jr., no one from the Kennedy family attended the marriage ceremony of their relative. Her husband was killed in action only four months later in World War II, and his younger brother Andrew Cavendish, married to Deborah Mitford, became the heir to the dukedom.

Popular on the social circuit and admired by many for her high spirits, though more traditional members of British society found fault with her boisterousness, the dashing young widow eventually became the misstress of Peter Wentworth-FitzWilliam, 8th Earl FitzWilliam. The couple planned to wed after Fitzwilliam's planned divorce. Instead, while on a trip to the south of France, Earl Fitzwilliam and Lady Hartington died in an airplane crash in Saint Bauzile, France.
