Francis Wemyss-Charteris, Lord Elcho

Brother Francis Wemyss-Charteris, Lord Elcho was the Grand Master Mason of the Grand Lodge of Scotland. He served from from 1786–1788.

Lord Elcho was the only son of Francis Charteris, second son of James Wemyss, 5th Earl of Wemyss. The fifth Earl's eldest son David Wemyss, Lord Elcho had been attainted for his part in the Jacobite Rising of 1745 so after the Earl's death in 1756 the earldom became forfeit.

Charteris was elected to Parliament for the Haddington district of burghs in 1780. From 1784 he was in opposition to the government of William Pitt the Younger.

In 1787 Charteris' uncle Lord Elcho (who but for his attainder would have been 6th Earl of Wemyss) died. As Charteris' father had not been attainted himself, he assumed the title as 7th Earl of Wemyss, with Charteris himself assuming the subsidiary title Lord Elcho. At the time eldest sons of Scottish peers were not allowed to represent Scottish constituencies in Parliament, and after a debate on the matter Charteris had to vacate his seat. Although it was later established that the Earldom of Wemyss remained forfeit and his father was not after all a Scottish peer, Charteris did not attempt to re-enter Parliament.

Charteris died on 20 January 1808 at Amisfield House, East Lothian, and was interred at St Mary's Collegiate Church, Haddington.
