and well-liked. Peerage At birth, as a son of the younger son of a peer, Grosvenor was entitled to no title or courtesy title at all. In 1963, his cousin William Grosvenor, 3rd Duke of Westminster died and Grosvenor's elder brother Gerald became 4th Duke. At this point, in view of the fact that he was likely to succeed his brother in the peerage, a Royal Warrant of Precedence was issued to allow Grosvenor to adopt the style of Lord Robert Grosvenor. Upon his brother's death in 1967, Robert duly became 5th Duke of Westminster. Although he took his seat in the House of Lords, he never spoke, something surprising in view of his political career. Westminster (as he was now known) was appointed honorary colonel of the North Irish Horse in 1971. Personal life On 3 December 1946, he married his second cousin, Hon. Viola Maud Lyttelton, a daughter of the 9th Viscount Cobham. They had three children, ten grandchildren and eleven great-grandchildren: Lady Leonora Mary Grosvenor (b. 1 February 1949). She married Thomas Patrick Anson, 5th Earl of Lichfield on 8 March 1975 and they were divorced in 1986. They have three children and two grandsons. Gerald Cavendish Grosvenor, 6th Duke of Westminster (22 December 1951 – 9 August 2016). He married Natalia Phillips on 7 October 1978. They had four children and six grandchildren. Lady Jane Meriel Grosvenor (b. 8 February 1953). She married Guy David Innes-Ker, 10th Duke of Roxburghe on 10 September 1977 and they were divorced in 1990. They have three children and three grandchildren. Lady Jane was presented to high society as a debutante at the prestigious International Debutante Ball at the Waldorf-Astoria Hotel in New York City in 1971. Grosvenor died on 19 February 1979 at Ely Lodge near Enniskillen in Northern Ireland. He was buried in the churchyard of Eccleston Church near Eaton Hall, Cheshire.
