Kenneth Sutherland, 3rd Lord Duffus. Richard Waitt, about 1712.
“Lord Duffus was a Scottish aristocrat who supported the Act of Union in 1707. However, during the 1715 Jacobite Rising he joined the rebels who wanted to restore the exiled Stuart dynasty. The Rising failed and Duffus’s estates were forfeited. He fled to the continent, but was captured and imprisoned in the Tower of London. Released in 1717, he later served in the Russian Imperial Navy where he rose to the rank of admiral.” via the National Galleries of Scotland.
