Frances Ruth Shand Kydd was the mother of Diana, Princess of Wales. She was the maternal grandmother of William, Prince of Wales and Prince Harry, Duke of Sussex, both respectively first and fifth in the line of succession to the British throne. Born into British aristocracy, she was the daughter of Maurice Roche, 4th Baron Fermoy, and Ruth Roche, Baroness Fermoy, a confidante of Queen Elizabeth the Queen Mother. Following her divorce from Viscount Althorp in 1969, and Diana's death in 1997, Shand Kydd devoted her later years to Catholic charity work after converting to Catholicism.
