Reading edition
Deinde hostes subegit, Scotiam usque Dunfoeder et Wertermorum terrestri exercitu vastavit, navali vero usque Catenes depopulatus est.—Sim. Dun. de Gestis Reg. Fugato deinde Owino rege Cumbrorum et Constantino rege Scotorum terrestri et navali exercitu Scotiam sibi subjugando perdomuit.—Sim. Dun. Hist. de Dun. Ec.
The Pictish Chronicle has—‘In xxxiv. ejus anno bellum Duinbrunde ubi cecidit filius Constantini.’ Though this is placed in the year of the invasion of Scotland, Constantin’s son was slain in the battle of Brunanburgh three years later, which seems to be the bellum Duinbrunde of the Chronicle. Kerimor was the name of one of the quarters into which Angus was divided, and is derived from Ceathramh, corrupted to Keri, a quarter. The Saxon equivalent is Feorde, probably corrupted to Werte.
