Lord Mackenzie of Kintail

Earl of Seaforth was a title in the Peerage of Scotland and the Peerage of Ireland. It was held by the family of Mackenzie from 1623 to 1716, and again from 1771 to 1781.

The Mackenzies trace their descent to Colin of Kintail (died 1278), and their name is a variant of Mackenneth. Kenneth, the twelfth head of the clan, was made Lord Mackenzie of Kintail in 1609, and his son Colin, who succeeded his father as 2nd Lord Mackenzie in March 1611, was created earl of Seaforth in 1623.

Colin's successor was his half-brother George (died 1651), who became the 2nd earl in 1633. George was alternately a royalist and a covenanter between 1636 and 1646, and was afterwards in Holland with Charles II, who made him Secretary of State for Scotland. His grandson, Kenneth, the 4th earl, followed James VII to France and was with the dethroned king in Ireland. Elevated by James in 1690, to Marquess of Seaforth and Earl (? Viscount or Lord) Fortrose (in the Jacobite peerage), he was sent to head a rising in Scotland. He was soon captured and imprisoned. He was released in 1697 and died in Paris in January 1701.

His successor was his son William, who joined the Jacobite standard at Braemar, during the rising of 1715, and then, having raised 3000 men, was present at the battle of Sheriffmuir and was appointed lieutenant-general of the northern counties. He also took part in the Jacobite enterprise of 1719, being wounded at Glenshiel. In 1716 he was attainted and his titles and estates forfeited; before his death in January 1740, he had been relieved of some of the penalties of his treason, although his titles were not restored. His son Kenneth (c. 1718–1761), who but for the attainder would have been the 6th earl, helped the English government during the rising of 1745, and was a member of parliament for some years.
