According to 19th-century historian Alexander Mackenzie, George Munro of Foulis was on 17 October 1410, before Hugh Fraser, 1st Lord Lovat the Sheriff of Inverness, served heir to his mother, Isobel Keith, in the lands of Lissera, Borrowston and Lybster in Caithness.
[2] Mackenzie also states that George Munro of Foulis obtained a charter under the Great Seal of king James I of Scotland dated at St Andrews on 22 July 1426, in which he had confirmed to him the land and baronies of Easter and Wester Fowlis (Foulis), Katewell, Contullich, Dann, Carbisdale, Inverlael, Findon and others.
The Munros and Dingwalls in response pursued the rising clans and the Battle of Bealach nam Broig took place in which the Kinlochewe clans of the MacIvers, MacAulays and MacLeays were almost utterly extinguished and the Munros and Dingwalls won a hollow victory: though the Earl's nephew had been rescued, they had lost a great number of men.
[3] George is believed to have been killed at the Battle of Bealach nam Broig in 1452 and this is likely as it is confirmed by records that he was dead by 1453.
[4] George Eyre-Todd writing in 1923 stated that George Munro of Foulis was killed during the wars of the Isles and Douglases,[5] the Battle of Brechin having been fought by supporters of the Douglases in 1452,[6] which was the same year that the Battle of Bealach nam Broig took place, but Eyre-Todd gives the year of Munro's death as 1454.
