m, and he was found guilty of treason and sentenced to
death. He escaped to England, and the date of his death is unknown. His
brother and assistant, Sir Alexander Boyd, was beheaded on the 22nd of
November 1469.

Boyd's son Thomas, earl of Arran, was in Denmark when his father was
overthrown. However, he fulfilled his mission, that of bringing the
king's bride, Margaret, to Scotland, and then, warned by his wife,
escaped to the continent of Europe. He is mentioned very eulogistically
in one of the Paston Letters, but practically nothing is known of his
subsequent history.

Lord Boyd's grandson Robert (d. c. 1550), a son of Alexander Boyd, was
confirmed in the possession of the estates and honours of his
grandfather in 1549, and is generally regarded as the 3rd Lord Boyd. His
son Robert, 4th Lord Boyd (d. 1590), took a prominent part in Scottish
politics during the troubled time which followed the death of James V.
in 1542. At first he favoured the reformed religion, but afterwards his
views changed and he became one of the most trusted advisers of Mary,
queen of Scots, whom he accompanied to the battle of Langside in 1568.
During the queen's captivity he was often employed on diplomatic
errands; he tried to stir up insurrections in her favour, and he was
suspected of participation in the murder of the regent Murray. He
enjoyed a high and influential position under the regent James Douglas,
earl of Morton, but was banished in 1583 for his share in the seizure of
King James VI., a plot known as the Raid of Ruthven. He retired to
France, but was soon allowed to return to Scotland. He died on the 3rd
of January 1590.

William, 8th or 9th Lord Boyd (d. 1692), was created earl of Kilmarnock
in 1661, and this nobleman's grandson William, the 3rd earl (d. 1717),
was a partisan of the Hanoverian kings and fought for George I. during
the rising of 1715. His son William, the 4th earl (1704-1746), was
educated in the same principles, but in 1745, owing either to a personal
affront or to the influence of his wife or to his straitened
circumstances he deserted George II. and joined Charles Edward, the
Young Pretender. The 4th earl fought at Falkirk and Culloden, where he
was made prisoner, and was beheaded on the 18th of August 1746. The
title of earl of Kilmarnock is now merged in that of earl of Erroll.

BOYD, ZACHARY (1585?-1653), Scottish divine, was educated at the
universities of Glasgow and St Andrews. He was for ma
