Arthur Elphinstone, 6th Lord Balmerino

In 1715 he joined the Uprising of 1715, and afterwards escaped to France, where he lived for 20 years. In 1744 he was one of the first to join the party of the Young Chevalier. He was Colonel of the 2nd troop of Horse Guards. He succeeded to the title of 5th Lord Coupar [S., 1607] on 5 January 1746. He succeeded to the title of 6th Lord Balmerinoch [S., 1606] on 5 January 1746. He fought in the Battle of Culloden on 16 April 1746, where he was taken prisoner. On 29 July 1746 he was tried for high treason, and found guilty (even though he pleaded not guilty).

On his death, the Lordship of Balmerinoch became extinct, while the Lordship of Coupar was subject to the attainder.
