On 10 April 1923 at
Beaumanor Hall, he married Dorothy Isabel Westenra Hastings (18 May 1899
Cirencester – 1 April 1988), daughter of The Hon. Osmund William Toone
Westenra Hastings, a younger son of the 14th
Earl of Huntingdon, and his wife Mary Caroline Campbell Tarratt, daughter of Daniel Fox Tarratt,
Gent. Lord and Lady Cambridge regularly attended major royal occasions, although they did not carry out royal duties. Lord Cambridge participated in the coronations of George V,
George VI, and
Elizabeth II. For many years he served as Royal Trustee of the British Museum. Lord Cambridge died on 16 April 1981 in
Little Abington, and was buried in the

World War II.
Issue Lord and Lady Cambridge had one daughter: Mary Ilona Margaret (24 September 1924 – 13 December 1999). Lady Mary was born at
Lowndes Square,
Kensington, when her parents were still known as Earl and Countess of Eltham. Lord and Lady Eltham lived on the edge of
Hyde Park, London, near Lord Eltham's cousin and his wife, the
Duke and
Duchess of York. The young Lady Mary was educated at home under the supervision of her grandmother, nanny, and governess. Often, she would be invited to play with her second cousins, the Princesses
Elizabeth and
Margaret of York, who lived near her by Hyde Park (specifically at 145 Piccadilly). When they were in London, she would also play with
George and
Gerald Lascelles, the children of the
Princess Royal, who were her second cousins. On 29 November 1934, she was a bridesmaid at the marriage of the
Duke of Kent to
Princess Marina of Greece and Denmark. When not in London and for the duration of the
London Blitz, the Cambridges sent Lady Mary to stay with her maternal grandmother, Mary Caroline Campbell Tarratt (died 1955), widow of Captain
the Hon. Osmond Westenra Hastings (1873–1933), at Hodcott House, their country house near
West Ilsley in
Berkshire. Her parents remained in London, as her father was a director of
Coutts & Company, a banking firm, in the city. When Mary was older, toward the end of the war, she became a volunteer nurse in the blitzed area of London. On 9 November 1951 at Kirtling,
Newmarket, Lady Mary married Peter Whitley (22 October 1923
Singapore – 25 January 2003) of Leighland House, Roadwater,
Watchet,
Somerset, a son of
Sir Norman Henry Pownall Whitley MC. After their marriage, the couple was given the Lord Cambridge's London townhouse in
St. James's Square. Peter pursued a career with
Distillers Company and became a managing director before his retirement in 1985. The couple had two children: • Sarah Elizabeth Whitley (born 30 November 1954), who married Timothy Felton (born 8 March 1954) on 18 September 1982 and has two daughters: Emily Ilona Felton (born 21 July 1985) and Chloë Amelia Felton (born 17 June 1987), the latest descendants of the Marquesses of Cambridge. • Charles Francis Peter Whitley (born 10 September 1961), who married Diana Hewitt (born 8 November 1953) on 25 May 1991. They have no children. Lady Mary regularly attended major royal occasions, but like her father, she did not carry out royal duties. Mary was a junior bridesmaid at the 1934 wedding of her father's first cousin,
Prince George, Duke of Kent to
Princess Marina of Greece and Denmark. She participated in the coronations of both King
George VI and Queen
Elizabeth II and attended the
Trooping the Colour every year between 1950 and 1999 (excluding 1955, when it was cancelled due to a rail strike). She attended the following royal marriages:
Princess Margaret to
Antony Armstrong-Jones, created
Earl of Snowdon (1960); the
Prince of Wales to Lady Diana Spencer (1981);
Princess Anne to Captain Mark Phillips (1973) and
Princess Anne's subsequent marriage to Commander
Timothy Laurence (1992);
Prince Andrew, Duke of York, to Sarah Ferguson (1986). ==Arms==
