Duncan MacGregor, was the son of Gregor,and grandson of Duncan Ladosach, called Donach Abberach, from having been immediately after his father's murder carried into Lochaber by his mother's friends, as were his two brothers, to Athol and Stratherarn, by other relations, in order to save them from also being killed.
He was a stout man of very fine appearance, and soon acquired a reputaion all over the Highlands. Duncan Dubh, dreaded that this young hero would make him answer for the murder of his father and grandfather and take back the lands he had gained by these murders. He endeavored to reconcile with Duncan Abberach. Locheil influenced Duncan to accept the offer Duncan Dubh made of his father's lands and those of Corriecharmaig and Tomachrochair in Glenorchy. These two Duncans were sworn to inviolable friendship in the presence of Locheil and several other chiefs at a meetingg of the friends of both held for that purpose in the Braes of Glenurchy.
Duncan Abberach's first wife was named Christian, and was a daughter from the family of MacDonald of Keppoch. They had a son who died young.
He married 2nd, a daughter to MacFarlane descended from the Lennox and had three sons by her.
1. Patrick his successor
2. Robert (whom the History of the Clan Gregor,says was a man of rare martial genius)
3. Alpin who married and had issue
The above named History, says that the first mention of Duncan Abberach is in the record of forfeitures September 8, 1569. He found favor with the Earl of Argyle as seen in this Bond of Maintenance:
