Edward Onslow (9 April 1758 – 18 October 1829)[1] was a British aristocrat, the younger son of George Onslow, 1st Earl of Onslow. In 1781, Onslow was involved in a homosexual scandal, and was forced to resign his seat in Parliament (by accepting the Stewardship of East Hendred) and flee to France.[2]
Onslow was educated at Christ Church, Oxford, matriculating in 1774. He briefly sat as Member of Parliament for Aldborough in 1780 and was elected the same year as a fellow of the Royal Society.[3]
On 7 March 1783, he married Marie Rosalie de Bourdeilles de Brantôme (d. 1842); one of their sons was George Onslow, the classical composer. Their son Maurice was the father of the French genre painter Édouard Onslow (1830-1904).[4] Marie was possessed of a considerable dowry, and Onslow spent the rest of his life as a country gentleman in France.
