In 1490,
James IV of Scotland granted to David Ross, nephew and heir of John Ross, and grandson of John Ross of
Balnagown, the lands of Strathoikel and
Strathcarron, which had formerly belonged to Morgan Neilson Mackay, who along with his brother Neil Neilson Mackay, had attempted in 1433 to take over the lands of Strathnaver from their cousin,
Angus Du Mackay, 7th of Strathnaver, but had been defeated and killed at the
Battle of Drumnacoub by Angus's forces. Although John Rivach Mackay received a remission from the king in 1494, the blood
feud with the Rosses appears to have continued as David Ross of Balnagown and Iye Roy Mackay of Strathnaver were summoned to appear before the
Earl of Argyll who was the
Lord High Chancellor of Scotland. On 4 October 1496, each of them were bound by extending their hand to Argyll in the king's name to keep the peace towards each other and that their "folks sal be harmless and skaithles", under the penalty of 500
merks if they failed. Notwithstanding the apparent reconciliation, David Ross of Balnagown and his brother Hucheon Ross, brought an action to the Lords of Council against the Mackays for spoils taken from their lands eight years earlier. On 15 March 1504, Iye Roy Mackay, 10th of Strathnaver secured from the king the lands of Ferencostrig,
Strathhalladale,
Creichmore,
Assent,
Coigach,
Gruids, and Strathfleet. On 15 February 1506, Iye Roy Mackay caused the
charter that had been granted by
Donald of Islay, Lord of the Isles in 1415 to the Mackays who laid claim to these lands. However, the
Lords of Council decided that the lands had belonged to
Euphemia II, Countess of Ross. The Mackays continued to
raid the Rosses well into the 16th century and did not stop until they became caught up in quarrels with their neighbours, the powerful Clan Sutherland. ==References==
