, viscount Tarbat, and first earl of Cromerty, a person eminent for his learning and for his abilities as a statesman, was descended from a branch of the family of Seaforth. He succeeded to the family estate on the death of his father sir John Mackenzie, and also to his unshaken fealty for Charles II. during whose exile he had a commission to levy what forces he could procure, to promote the restoration. After that event, he was made one of the senators of the college of justice, clerk register of the pri% 7 y council, and justice-general, an office which had been hereditary in the family of Argyle, till it was surrendered in the preceding reign. James II. made him a baron and viscount, but on the abdication of that monarch, whom it woukl appear he had favoured too much, he lost his office of lord-register for some time, until king William III. was pleased to restore it in 1692, being no stranger to his abilities. In queen Anne’s reign, 1702, he was constituted secretary of state, and the following year was advanced to the dignity of earl of Cromerty. He died in 1714, at the age of eighty-three, or, according to another account, eighty-eight.
