The policy followed by King William, with regard to these earldoms, was checked for a time by the unfortunate result of his attempt in 1174 to recover possession of the northern provinces of England, when he was taken prisoner, and only recovered his liberty by surrendering the independence of his kingdom; but soon after his liberation, when he returned to Scotland, he appears to have created two new earldoms, which he bestowed upon his brother David. The first was the earldom of Garvyach or Garrioch in Aberdeenshire, formed from the districts surrounding the ancient fortification of Dunideer, and extending between the river Don and its tributary the Ury. The second was the earldom of Levenach or Lennox, and consisted of the northern part of the old Cumbrian kingdom, which appears to have received a Gaelic population, and is nearly represented by the county of Dumbarton.[82] These districts were probably at the time in the hands of the Crown. The earldom of Garvyach passed on David’s death to his son John the Scot, after whose death it again reverted to the Crown, and was eventually granted as a lordship to the earls of Mar. The earldom of Levenach does not appear to have remained long in Earl David’s possession, as we find it emerging in the possession of a line of Celtic earls, the first of whom, Aluin, must have received it as early as the year 1193. Earl David was invested with the English earldom of Huntingdon on the death of its then possessor, Simon de Senlis, in 1184; and it is probable that on that occasion he resigned the earldom of Lennox in favour of the head of its Gaelic population.[83] [Sidenote: Earldoms of Ross and Carrick.] In 1179 William the Lion brought the people of Ross under more complete subjection to the Crown, and built two royal castles within its bounds, but he appears to have retained the earldom in his own hands, as the Count of Holland complains that he had been deprived of it, although he had never been forfeited. His grievance was probably not a very substantial one, as it is very unlikely that he either had obtained or could obtain practical possession of it. Seven years after the king formed a second earldom out of the territory of the old Cumbrian kingdom, at its southwestern extremity, where it bordered upon the Gaelic district of Galloway, and appears to have received a Gaelic population from thence. This was the district of Carrick, which he bestowed as an earldom upon Duncan, son of Gilbert, and grandson of Fergus, the Celtic Lord of Galloway. [Sidenote: Earldom of Caithness.]
