Lady Mary Fox

Lady Mary Fox (née FitzClarence; 19 December 1798 – 13 July 1864) was an illegitimate daughter of King William IV of the United Kingdom by his mistress Dorothea Jordan. In later life she became a writer.

Marriage

Mary FitzClarence was born in Bushy House as the fourth child and second daughter of the then Prince William, Duke of Clarence, and his companion Dorothea Jordan. She was "a fine looking, brown girl with a pleasant countenance and manners". In 1820, her younger sister Elizabeth was courted by Charles Richard Fox, the eldest but illegitimate son of Lord and Lady Holland. His parents did not consent to the match, but four years later approved of his relationship with Mary.

The couple married on 19 June 1824 in St George's, Hanover Square, London. Lady Holland worried that she might be "a sickly subject" and wished that the "roturier blood of the mother might have mitigated the royal constitutions". Her mother-in-law wrote on 31 August that her son, "though fond of her, he only considers her as an auxiliary to his medals and other possessions, not as a principal", but concluded that "it will all do well; as she is very winning, and very firm, and sincerely fond of him." The pair established their household in Little Holland House by 1827. They moved to Canada in September 1829 when Charles resumed active army service.
