Robin Henry Charles Neville was born on 29 January 1932 as the only son of Henry Seymour Neville, 9th Baron Braybrooke and Muriel Evelyn Manning. When he was seven years old, during World War II, he was evacuated to Llandovery, Carmarthenshire in South West Wales and stayed at the home of a retired guard of the Great Western Railway. While staying in Llandovery he developed an interest in railways. He later had a miniature railway built at Audley End. He was educated at Eton College and served in the Rifle Brigade. From 1951 to 1952 he served in the 3rd Battalion King's African Rifles in Kenya and Malaya. When he returned to England after his military service, he studied history at Magdalene College, Cambridge, graduating in 1955. He held honorary degrees from the University of Essex and Anglia Ruskin University. A trained pilot, he operated a small airfield on his estate called the Audley End International Aerodome. Although the House of Neville owns the Audley End estate, Audley End House was sold to English Heritage in 1948 by Lord Braybrooke's father, the 9th Baron Braybrooke. Robin became Deputy Lieutenant of Essex from 1980 to 1992. Lord Braybrooke was married three times. In 1955 he married his first wife, Robin, with whom he had five daughters: Amanda Muriel May Neville, Caroline Emma Neville, Henrietta Jane Neville, Victoria Neville, and Arabella Neville. One of his daughters from his first marriage, Henrietta, died in a riding accident. He had three daughters with his second wife, Linda: Sara Lucy Neville, Emma Charlotte Neville, and Lucinda Octavia Neville. He married his third wife, Perina, in 1998. He succeeded his father and became the 10th Baron Braybrooke in 1990. From 1992 to 2000 he served as Lord Lieutenant of Essex. He died on 5 June 2017 at Abbey House, near Audley End House, in Saffron Walden. A private funeral was held at the Church of St Mary the Virgin on 21 July 2017. He was succeeded to the Barony by his fifth cousin, Richard Neville. His 6,000 acre estate went to Louise Newmann, due to a ruling in the will of the 7th Baron Braybrooke. His eldest daughter, Amanda, criticised primogeniture, which forbid daughters from inheriting titles and estates from their fathers.
