Annals of Ulster, A.D. 839, 840, 925, 928, 934.
These colonies were governed by earls, not kings, and their dependency on the kingdom of Dublin is clearly shown by certain entries in the Annals. In 926 a Viking fleet at Linn Duachaill (on the coast of Louth) was commanded by Albdann (O.N. Halfdanr), son of Guthfrith (King of Dublin, 920-933). Later, when part of Albdann’s army was besieged at Ath Cruithne (near Newry), Guthfrith went with his forces to relieve it. In 927 the “foreigners of Linn Duachaill” accompanied Guthfrith when he marched on York. See Steenstrup, op. cit., III., p. 115.
