Douglas, James, second duke of Queensberry and first duke of Dover (1662–1711), politician, was born at Sanquhar Castle, Dumfriesshire, on 18 December 1662, the eldest son of William Douglas, third earl and first duke of Queensberry (1637–1695), and Lady Isabel Douglas (d. 1691), sixth daughter of William Douglas, first marquess of Douglas. He entered his studies at Glasgow University in 1676 and thereafter travelled in continental Europe, returning in 1684. On 1 December 1685, aged nearly twenty-three, he married Lady Mary Boyle (1670/71–1709), second daughter of Charles Boyle, styled Viscount Dungarvan, and Jane Seymour, daughter of William, duke of Somerset; the marriage produced four sons and five daughters. His title was lord and then earl of Drumlanrig, before he succeeded his father in March 1695.
