On 28 September 1974, Arran married Eleanor van Cutsem, daughter of
Bernard van Cutsem and
Lady Margaret Fortescue, and granddaughter of
Hugh Fortescue, 5th Earl Fortescue, and heiress of the Fortescue seat of
Castle Hill, in Devon. She was appointed a Member of the
Order of the British Empire (MBE) in the
Queen's Birthday Honours 2008. Lord and Lady Arran run the Fortescue family's stately home,
Castle Hill House and gardens in Devon, as a venue for weddings and corporate hospitality. He has no son, but has two daughters: • Lady Laura Melissa Fortescue-Gore (born 14 June 1975), who married Major James Duckworth-Chad (maternal great-grandson of
7th Earl Spencer) on 16 October 2004. They have four children. • Lady Lucy Katherine Fortescue-Gore (born 26 October 1976)
Heir presumptive Since Lord Arran has no sons by his wife, and all other lines of descent from the 4th Earl of Arran have died out, his
heir presumptive is currently his very distant cousin, William Henry Gore (born 1950), who lives in Australia, descended from the youngest brother of the 4th Earl. ==Arms==
