Angus Roy Mackay, 9th of Strathnaver

Angus Roy Mackay, 9th of Strathnaver (died 1486), was the ninth chief of the ancient Clan Mackay, a Scottish clan of the Scottish Highlands.

Early life Angus Roy Mackay, 9th of Strathnaver, was the eldest son of Neil Mackay, 8th of Strathnaver, and his wife who was a daughter of George Munro, 10th Baron of Foulis, chief of Clan Munro. His maternal grandmother, through Munro of Foulis, was a daughter of Ross of Balnagown, chief of Clan Ross. According to historian Angus Mackay it is not known exactly why Mackay chose to support the Keiths, but it could have been partly because of the prospect of plunder, but also because at the time Sir Gilbert Keith of Inverguie was collector of customs for Caithness, Strathnaver and Sutherland, and in this function might have crossed the Gunns and befriended the Mackays, securing Mackay's help. According to historian Angus Mackay the evidence is ample that the Mackays managed to recover some of the lands in Ross-shire that had belonged to their relatives and enemies, Neil Neilson Mackay, his brother Morgan Neilson Mackay and Neil and Morgan's father-in-law Murray of Cubin, all three of whom had been defeated and killed by the Mackays of Strathnaver at the Battle of Drumnacoub in 1433.
