Baron Fermoy

Baron Fermoy is a title in the Peerage of Ireland. It was created by Queen Victoria in 1856 for Edmond Roche, who represented County Cork and Marylebone in the House of Commons and also served as Lord Lieutenant of County Cork. His younger son, the third Baron, sat as Member of Parliament for Kerry East. He was succeeded by his son, the fourth Baron. He notably represented King's Lynn in Parliament. As of 2010 the title is held by his grandson, the sixth Baron, who succeeded his father in 1984.

Diana, Princess of Wales, was a great-great-granddaughter of the first Baron Fermoy through her mother, The Honourable Frances Shand Kydd. She was the daughter of the fourth Baron Fermoy, a friend of King George VI and the elder of the twin sons of the American heiress Frances Work and her first husband, Hon. James Boothby Burke Roche, who, after their divorce, became third Baron Fermoy. Her maternal grandmother Ruth Roche, Baroness Fermoy (née Ruth Sylvia Gill), was a confidante and lady-in-waiting to Queen Elizabeth (later the Queen Mother), and founder of the annual King's Lynn Festival (of classical music) in Norfolk, England.
