After the forfeiture of the Lords of the Isles, and the failure of the successive attempts which were made to retrieve their fortunes, different clans occupied the extensive territories which had once acknowledged the sway of those insular princes. Of these some were clans, which, although dependent upon the Macdonalds, were not of the same origin as the race of Conn; and, with the exception of the Macleods, Macleans, and a few others, they strenuously opposed all the attempts which were made to effect the restoration of the family of the Isles, rightly calculating that the success of such opposition would tend to promote their own aggrandisement. Another class, again, were of the same origin as the family of the Isles; but having branched off from the principal stem before the succession of the elder branches reverted to the clan, in the person of John of the Isles, during the reign of David II., they now appeared as separate clans. Amongst these were the Macalisters, the MacIans, and some others. The Macalisters, who are traced to Alister, a son of Angus Mor, inhabited the south of Knapdale and the north of Kintyre. After the forfeiture of the Isles they became independent; but being exposed to the encroachments of the Campbells, their principal possessions were ere long absorbed by different branches of that powerful clan. The MacIans of Ardnamurchan were descended from John, a son of Angus Mor, to whom his father conveyed the property which he had obtained from the crown. The Macdonalds of Glencoe are also MacIans, being descended from John Fraoch, a son of Angus Og, Lord of the Isles; and hence their history is in no degree different from that of the other branches of the Macdonalds. A third class consisted of the descendants of the different Lords of the Isles, who still professed to form one clan, although the subject of the representation of the race soon introduced great dissensions, and all adopted the generic name of Macdonald in preference to secondary or collateral patronymics. We shall now endeavour to give a short account of the different branches of the Macdonalds, from the time of the annexation of the Lordship of the Isles to the crown in 1540. Since the extinction of the direct line of the family of the Isles, in the middle of the 16th century, Macdonald of Sleat, now Lord Macdonald, has always been styled in Gaelic _Mac Dhonuill nan Eilean_, or Macdonald of the Isles.[149] As the claim of Lord Macdonald, however, to this distinction has been keenly disputed, we shall here lay before the reader, as clearly as possible, the pretensions of the different claimants to the honour of the chiefship of the clan Donald, as these have been very fairly stated by Mr Skene.
