Lord Mountbatten was born at King's College Hospital in London[1] as the eldest son of Patricia Knatchbull, Mountbatten, later 2nd Countess Mountbatten of Burma, and John Knatchbull, 7th Baron Brabourne.[2]
Mountbatten was educated at the Dragon School, in Oxford, and Gordonstoun School, Elgin, Moray, Scotland. He subsequently attended the University of Kent in southeast England.
He followed his father into the British film industry in the 1970s, working as location manager on A Bridge Too Far and associate producer of Death on the Nile and the television serial Quatermass.[3]
On the death of his father on 23 September 2005, he became the 8th Baron Brabourne, of Brabourne in the County of Kent, in the peerage of the United Kingdom. He also succeeded to the Knatchbull Baronetcy, of Mersham Hatch in the County of Kent, in the baronetage of England. On the death of his mother on 13 June 2017, he became Earl Mountbatten of Burma, also a title in the peerage of the United Kingdom created for his grandfather, Admiral of the Fleet Lord Louis Mountbatten.
He is a descendant of Queen Victoria, whose second daughter Princess Alice of the United Kingdom was his maternal great-great-great-grandmother. He is also a second cousin to Charles III, through his mother and Charles' father, Prince Philip, Duke of Edinburgh, who was his godfather. Mountbatten is the godfather of Philip's grandson, the Prince of Wales. He is also related to author Jane Austen, as his father, John Knatchbull, 7th Baron Brabourne, was a direct descendant of her brother Edward Austen Knight.[4]
Mountbatten is married to Penelope Meredith Eastwood[5] (born 16 April 1953), a daughter of Reginald Wray Frank Eastwood (1912–1980), a self-made millionaire former butcher who founded the Angus Steakhouse chain, and Marian Elizabeth (1926–2020), née Hood.[6] They were wed on 20 October 1979 at Romsey Abbey, Romsey, less than two months after the IRA murdered his 79-year-old maternal grandfather, Louis Mountbatten, 1st Earl Mountbatten of Burma; his 14-year-old younger brother, Nicholas Knatchbull; and his 83-year-old paternal grandmother, Doreen Knatchbull, Dowager Lady Brabourne.
The family home is Broadlands, also in Hampshire.
