Lord Archibald James Edward Steuart Douglas of Douglas (1748-1827) was the eldest son of Lady Jane Steuart and her husband Colonel Douglas (after 1759 Sir John Steuart, 3rd Baronet of Grandtully). He was educated at Rugby and at Westminster and in 1761 inherited the estate of Douglas from his uncle Archibald, first Duke of Douglas (1694-1761), whose sister was Lady Jane Steuart. He assumed the surname Douglas at that stage. His succession was disputed by the Duke of Hamilton, Lord Douglas Hamilton and Sir Hew Dalrymple of North Berwick, in what became known as the 'Douglas Cause'. The Court of Session decided against him in 1767 but the decision was reversed in 1769 and finally settled in 1779 by the House of Lords. He became MP for Forfarshire, 1782-1790, and in 1790 was created a peer in the House of Lords with the title Lord Douglas of Douglas. He married first in 1771, Lady Lucy Graham (d 1780), and second, in 1783, Lady Frances Scott (d 1817). He died on 26 December 1827.
