David_Wemyss,_6th_Earl_of_Wemyss

David Wemyss, Lord Elcho and de jure 6th Earl of Wemyss (12 August 1721 – 29 April 1787), was a Scottish peer and Jacobite, attainted for his part in the 1745 Rising and deprived of titles and estates.
One of the few Jacobites excluded from the 1747 Act of Indemnity, his attempts to return home were unsuccessful and he spent the rest of his life in France and Switzerland. His wife Sofia (1756–1777) died in childbirth; Elcho left no legitimate children and when he died in Paris in 1787, his property passed to a younger brother.
His record of the 1745 Rising or A short account of the affairs of Scotland in the years 1744, 1745, 1746, is now considered a key contemporary source for the Rising.
