“ The territories of the Mackenzies were greatly increased by Kenneth, their twelfth chief, who was created a peer, under the title of Lord Mackenzie of Kintail, 19 Nov. 1609, and on the abandonment of the scheme for the colonisation of Lewis, obtained possession of that island. George, third lord Mackenzie, succeeded to the earldom of Seaforth on the death of his half-brother, Colin, first earl, without male issue, 15 April 1683. ”
