Twenty years later, Nicholas Sutherland of Torboll, and his brother, Donald, were both dead and so the lands went to the third son of Angus, Hugh.

[3] In 1476, the Earl of Sutherland was in dispute with Sir Robert Crichton of Sanquhar over the property of the lands of "Cragton", which according to Fraser was perhaps Culmaily in Golspie.

The first was at the instance of Sir Gilbert Keith of Inverugie, for the reduction of a letter of reversion granted to him by the earl of £40 worth of lands in Strath Ullie in Sutherland; and secondly, a charter made by Sir Gilbert in favour of the earl for £40 worth of lands in Subister and others, in Caithness.

[5] According to historian D. M Rose, the 7th and 8th Earls of Sutherland did little to advance their family's reputation, leaving their kinsman the Murays of Culbin, Pulrossie and Aberscross to fight their battles.

Fraser stated that there is no record of the proceedings, but a proclamation of the brief was duly made, and the earl, having been declared incapable of managing his own affairs, was placed under the care of a tutor.

The last record was an order issued in February 1499 by the Lords of Council requiring Sir James Dunbar of Cumnock to bring the earl and his minor son to the king, their expenses being paid for.

Fraser stated that this Fingole has not been identified but that the wife of Celestine MacDonald had a similar name and therefore suggested a descent from that family.

[3] According to 19th-20th century historian Angus Mackay, the earl was, if not married to, at least hand-fasted with a daughter of the chief of the Clan Ross of Balnagown Castle.
