Og, the ancestor of the Macdonalds of Glencoe. [Illustration: MACDONALD. (Tartan)] Angus, as we have already seen, had all his life been a steady friend to the crown, and had profited by his fidelity. But his son John does not seem to have inherited the loyalty along with the power, dignities, and possessions of his father. Having had some dispute with the Regent concerning certain lands which had been granted by Bruce, he joined the party of Edward Baliol and the English king; and, by a formal treaty concluded on the 12th of December 1335, and confirmed by Edward III. on the 5th October 1336, engaged to support the pretensions of the former, in consideration of a grant of the lands and islands claimed by the Earl of Moray, besides certain other advantages. But all the intrigues of Edward were baffled; Scotland was entirely freed from the dominion of the English; and, in the year 1341, David II. was recalled from France to assume the undisputed sovereignty of his native country. Upon his accession to the throne, David, anxious to attach to his party the most powerful of the Scottish barons, concluded a treaty with John of the Isles, who, in consequence, pledged himself to support his government. But a circumstance soon afterwards occurred which threw him once more into the interest of Baliol and the English party. In 1346, Ranald of the Isles having been slain at Perth by the Earl of Ross, as already mentioned, John, who had married his sister Amy, immediately laid claim to the succession. The government, however, unwilling to aggrandise a chief already too powerful, determined to oppose indirectly his pretensions, and evade the recognition of his claim. It is unnecessary to detail the pretexts employed, or the obstacles which were raised by the government. Their effect was to restore to the party of Baliol one of its most powerful adherents, and to enable John in the meanwhile to concentrate in his own person nearly all the possessions of his ancestor Somerled.
