The Clan Donald derive their origin from a son of Reginald, who appears to have inherited South Kintyre, and the island of Islay; but little is known of their history until the annexation of the Isles to the crown in the year 1266. According to Highland tradition, Donald made a pilgrimage to Rome to do penance, and obtain absolution for the various enormities of his former life; and, on his return, evinced his gratitude and piety by making grants of land to the monastery of Saddel, and other religious houses in Scotland. He was succeeded by his son, Angus Mor, who, on the arrival of Haco with his fleet, immediately joined the Norwegian king, and assisted him during the whole of the expedition; yet, when a treaty of peace was afterwards concluded between the kings of Norway and Scotland, he does not appear to have suffered in consequence of the part which he took in that enterprise. In the year 1284 he appeared at the convention, by which the Maid of Norway was declared heiress of the crown, and obtained as the price of his support on that occasion a grant of Ardnamurchan, a part of the earldom of Garmoran,[141] and the confirmation of his father’s and grandfather’s grants to the monastery of Saddel. Angus left two sons, Alexander and Angus Og (_i.e._, the younger). Alexander, by a marriage with one of the daughters of Ewen of Ergadia, acquired a considerable addition to his possessions; but having joined the Lord of Lorn in his opposition to the claims of Robert Bruce, he became involved in the ruin of that chief; and being obliged to surrender to the king, he was imprisoned in Dundonald Castle, where he died. His whole possessions were forfeited, and given to his brother, Angus Og, who, having attached himself to the party of Bruce, and remained faithful in the hour of adversity, now received the reward of his fidelity and devotion. Angus assisted in the attack upon Carrick, when the king recovered “his father’s hall;” and he was present at Bannockburn, where, at the head of his clan, he formed the reserve, and did battle “stalwart and stout,” on that never-to-be-forgotten day. Bruce, having at length reaped the reward of all his toils and dangers, and secured the independence of Scotland, was not unmindful of those who had participated in the struggle thus victoriously consummated. Accordingly, he bestowed upon Angus the lordship of Lochaber, which had belonged to the Comyns, together with the lands of Durrour and Glencoe, and the islands of Mull, Tyree, &c., which had formed part of the possessions of the family of Lorn. Prudence might have restrained the royal bounty. The family of the Isles were already too powerful for subjects; but the king, secure of the attachment and fidelity of Angus, contented himself with making the permission to erect a castle or fort at Tarbet in Kintyre, a condition of the grants which he had made. This distinguished chief died early in the fourteenth century, leaving two sons, John his successor, and John
