See Fionnla Dubh Mac Gillechriosd
According to the Rev. John Macrae, the founder of the Clan Macrae of Kintail was Fionnla Dubh Mac Gillechriosd (Black Finlay, the son of Christopher), who was removed by two or three generations from the man who came from Clunes. Finlay Dubh was a contemporary of Murdo Mackenzie, fifth chief of Kintail, who died in 1416, leaving an only child to succeed him. This child's name was Alexander, and is known as Alister Ionraic (Alexander the Upright). Alexander being a minor at the time of his father's death, was sent as a ward of the King to the High School in Perth, probably after the Parliment which was held at Inverness by James I. in 1427. During his absence at school, the Constable of Ellandonan Castle, whose name was Macaulay, appears to have been left in charge of affairs, but through the misconduct and oppression of certain illegitimate relatives of the young chief, serious troubles arose in Kintail. The Constable's position becoming now somewhat difficult, he became anxious for the return of his young master, and as he was himself unable to leave his post he proposed Finlay Dubh as the most suitable person to go to Perth to bring the young chief home, "who was then there with the rest of the King's ward children." This choice was approved by the people. Finlay accordingly went to Perth, and prevailed upon Alexander to escape from school without the consent or knowledge of the master. To avoid pursuit they went to Macdougal of Lorn instead of going straight home. Macdougal recieved them kindly, and Alexander made the acquaintance of his daughter, and afterwards married her. In due time they arrived in Kintail, and by Finlay's councel and help, the oppressors of the people were soon brought under subjection, and order established throughout Mackenzie's land. The good counsel and judicious guidance of Finlay Dubh was not lost upon Alexander, who became a good, just and prosperous ruler, and greatly increased the power and influence of the House of Kintail.
