William Cavendish, 3rd Duke of Devonshire

William Cavendish, 3rd Duke of Devonshire, KG, PC (26 September 1698 – 5 December 1755) was a British nobleman and Whig politician, the son of William Cavendish, 2nd Duke of Devonshire and Hon. Rachel Russell.

He married Catherine Hoskins (or Hoskyn) (d. 8 May 1777) on 27 March 1718. They had seven children:

• Lady Caroline Cavendish (22 May 1719 – 20 January 1760), married William Ponsonby, 2nd Earl of Bessborough and had issue
• William Cavendish, 4th Duke of Devonshire (1720 – 2 October 1764)
• Lord George Augustus Cavendish (d. 2 May 1794), died unmarried
• Lady Elizabeth Cavendish (bef. 1727–1796), married Hon. John Ponsonby and had issue
• Field Marshal Lord Frederick Cavendish (c. 1729 – 21 October 1803), died unmarried
• Lord John Cavendish (c. 1734–1796)
• Lady Rachel Cavendish (d. 1805), married Horatio Walpole, 1st Earl of Orford.

He was made a Privy Counsellor (PC) in 1731, and served as Lord Privy Seal from 1731 to 1733. He was invested as a Knight of the Garter (KG) in 1733. In 1739, he was enlisted as a founding governor for the new children's charity, the Foundling Hospital in London, which aimed to alleviate the problem of babies being abandoned by destitute mothers and ended up becoming a centre for British art and music.

William Cavendish is also notable as the most recent common ancestor of Prince Charles and his first wife, Lady Diana Spencer. Charles and Diana were seventh cousins once removed as Charles descends from William’s son, the 4th Duke, and Diana was descended from William’s daughter, Lady Elizabeth.
