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 2013[update] the title is held by his grandson, the sixth Baron, who succeeded his father in 1984. The first baron was named after his relative Edmund Burke and are descended from the House of Burke
Diana, Princess of Wales, was a great-great-granddaughter of the first Baron Fermoy through her mother, Frances Shand Kydd.

James Boothby Burke Roche, who, after their divorce, became the third Baron Fermoy. Diana's maternal grandmother, Ruth Roche, Baroness Fermoy, was a confidante and lady-in-waiting to the Queen Mother, and the founder of the annual King's Lynn Festival (of classical music) in Norfolk, England.
