880] as the reward of their valour, which are supposed to be occupied by their descendants at the present day.[62] With the retreating emigrants, the last semblance of independence departed from the Britons of the north; and upon the death of their king Donald, who was probably a descendant of Kenneth’s daughter, Constantine the Second experienced little difficulty in procuring the election of his own brother Donald to fill the vacant throne.[63] [Sidenote: A. D. 908.] Henceforth a branch of the MacAlpin family supplied a race of princes to Strath-Clyde; and although for another hundred years the Britons of that district remained in a state of nominal independence, they ceased to exist as a separate people, appearing, on a few subsequent occasions, merely as auxiliaries in the armies of the Scottish kings. Fifteen years after his victory over Ivar in Strathearn, Constantine was called upon for the last time to oppose an inroad of the Northmen. At the beginning of the tenth century by far the most celebrated of all the northern leaders were the Hy Ivar or grandsons of Ivar, and sons, apparently, of a daughter of that chieftain married to a Scottish Viking, who seems to have succeeded Ketil in the dominion of Inch Gall or the Hebrides. Driven from Dublin after its capture by the Irish king Malfinan, in 902, they appear, like Thorstein, to have sought the shelter of the Western Isles; and it was owing probably to the loss of their Irish possessions that they attempted, under the command of the younger Ivar, to establish themselves upon the Scottish coasts in 903, from whence, as has been already stated, they were expelled in the following year.[64] [Sidenote: A. D. 904.] Ten years passed away before the Hy Ivar again appear on the scene. Reginald, who had now succeeded to the leadership of the family, defeated and destroyed the fleet of a rival Viking, Barith MacNocti, [Sidenote: A. D. 914.] in an engagement off the Isle of Man; and from the date of this victory the Norsemen again began to collect upon the Irish coasts, arriving every year in increasing numbers. Three years later, Reginald, known by this time as king of the Dugall, landed at Waterford [Sidenote: A. D. 917.] to assume the command, whilst his brother Sitric, appearing upon the coasts of Leinster, soon succeeded in re-establishing the power of his family over their former dependency of Dublin; and in the following year Reginald and his brother Godfrey, with the Jarls Ottir and Gragraba, who seem to have recently returned from an unsuccessful inroad upon the coast of Wales, leaving the harbour of Waterford, sailed for the northern shores of England to assert the claim of the king of the Dugall as heir of his kinsman, the Danish Halfdan, to the fertile lands of Northumbria.[65] [Sidenote: A. D. 918.]
