It may be gathered from the circumstances of his early life that Macbeth did not attain even to the position of Mormaor without a struggle. The two sons of Ruadhri--Roderic or Rory--the first known member of the Moray family, succeeded according to the Gaelic custom, Finlay filling the office of Tanist during the lifetime of his brother Malbride. He was slain, as has been already mentioned, by his nephews, who evidently intended to retain the right of succession within their immediate branch of the family; Gilcomgain, who must have been chosen Tanist on his brother’s accession to the Mormaordom, following Malcolm to the exclusion of Finlay’s son, Macbeth, whose right to the Tanistship was undoubted, and who must have thus found himself shut out from the seniority to which he was fully entitled to aspire as the representative of the junior branch of Rory’s family. The union of Gilcomgain with a daughter of the MacAlpin family must have still further strengthened his position, and as Macbeth is subsequently entitled _Dux_ by the contemporary Marianus, it may be conjectured that if he filled the office of _Toshach_--Duke or Constable of the kingdom--during the reign of Duncan, it may have been conferred upon him originally as the natural opponent of the rival line of Kenneth MacDuff, with which the kinsman who had supplanted him was closely connected. The last two years of Malcolm’s reign, however, witnessed the deaths of Gilcomgain and of his wife’s brother; and though the name of the Mormaor’s enemy is not mentioned, it is hardly possible to doubt, that when he was surprised and burnt with fifty of his followers, it was the deed of Macbeth avenging the murder of his father, and re-asserting his claim upon the Mormaorship. The subsequent death of Boedhe’s son transferred his claims upon the throne to his sister Gruoch, whose marriage with Macbeth reversed the position in which the Mormaor had hitherto stood, and placed him in the position of Gilcomgain. Henceforth his interest was closely bound up with the family to which he had hitherto been hostile, though, had Duncan been prosperous, his fidelity might have stood the test. It was the disastrous career of this unfortunate prince which first seems to have aroused the ambition of Macbeth; but even then his hostility was secret. It was not in open battle that Duncan lost his life, nor was the crown of Scotland the prize of the victor in a hard fought field, the final scene in “the Smith’s bothy” being strongly suggestive of treachery.
