According to tradition, the Macraes were originally from Ireland, and shared a common ancestry with the Mackenzies and Macleans. The Macraes were said to have originated from Clunes, which is located near the southern shore of the Beauly Firth, and was within the lordship of Lovat. Alexander Macrae stated that these traditions likely refer to a period sometime in the middle of the 13th century. According to John Macrae, after a violent dispute arose between the Macraes and more powerful Frasers of Lovat, three sons of the Macrae chief set off for new lands. One of the sons settled in Brahan, near Dingwall (later the site of Brahan Castle); another settled in Argyll; and the other settled in Kintail.
