Clan Information: Probably the earliest authentic history of Mackintosh is traceable to Shaw or Seach MACDUFF, a Cadet son of the third Earl of Fife. The son of MACDUFF, for his support of Malcolm IV, was awarded the lands of Petty and Breachley in Invernesshire and was appointed Constable of the Castle thereto. Assuming the name "Mac-an-Toisch", which means "Son of the Thane or Chief", he began his own Clan. The Clan support of James I in 1429 resulted in large tracts of land being settled on the Mackintoshes. Clan Mackintosh was involved in the "Battle of the Thirty", a mass trial by combat, which was held under the judicial control of the King in 1396 on the North Inch of Perth, in which Clan Mackintosh regained all lands taken from the Shaws.
