The Earls of Sutherland by Sir Robert Gordon
See Fionnla Dubh Mac Gillechriosd
John, son of Fionnla Dubh, had a daughter Margaret, who was lady-in-waiting to the Countess of Sutherland, and who appears to have married John Gordon of Grummoy, son of Adam Gordon, Dean of Caithness, son of Alexander, 1st Earl of Huntley.
Reference is made at some length to this Margaret in The Earls of Sutherland by Sir Robert Gordon, who speaks of her in the highest terms. The Rev. John Macrae's account of the marriage does not agree with Sir Robert's in every point, but there is no doubt that Margaret was related to the Macraes of Kintail.
