James Hay, 15th Earl of Erroll

James Hay, 15th Earl of Erroll (20 April 1726 – 3 July 1778) was a Scottish nobleman and the son of William Boyd, 4th Earl of Kilmarnock.

Biography

Born James Boyd, the eldest son of William Boyd, 4th Earl of Kilmarnock and Lady Anne Livingston at Falkirk on 26 April 1726, he was known from 1728 to 1746, while his father was Earl of Kilmarnock, by the courtesy title of Lord Boyd.

During the 1745 Jacobite Rebellion his father, the Earl, sided with the Young Pretender, despite both James and his brother William then holding commissions under George II; James in the army, William in the navy. Remaining loyal to the Hanoverians, James then served at the Battle of Culloden, fighting on the opposite side to his father. During the rout following the Jacobite defeat, the Earl was captured and taken into the government camp, dishevelled and bareheaded, where he was reportedly recognised by James, who placed his own hat upon his father's head. This was the last time they were to meet, as the Earl was then transported to London where he was tried for treason and executed the following year; forfeiting all his lands and titles and thus depriving James of his inheritance.

In 1751 however, although the Earldom was abolished, James was permitted to inherit the Kilmarnock estates. These included Dean Castle, the former family seat which had been gutted by a fire in 1735. Trying to recoup some of his father's debts (which he had also inherited), James sold the ruined castle to the 13th Earl of Glencairn.

On 19 August 1758 he succeeded his maternal great-aunt, Mary Hay, 14th Countess of Erroll as the 15th Earl of Erroll, simultaneously changing his surname from Boyd to Hay, as he and his descendants were henceforth known. Along with the title Earl of Erroll he also held the ceremonial hereditary office of Lord High Constable of Scotland.

Between 1770 and 1774 he served as a Representative Peer in the House of Lords.

He died on 3 July 1778 at Callendar House, aged fifty-two.
