As a consequence of Rǫgnvaldr's vassalage to the English Crown, and his role as guardian of the English seaways, it is probable that Islesmen were involved in far fewer predatory actions along the English and Irish coasts. At about the same time, several south-western Scottish magnates received grants in the north of Ireland. These included three of Rǫgnvaldr's Meic Fergusa kinsmen: Alan fitz Roland, Lord of Galloway, Alan's brother Thomas fitz Roland, Earl of Atholl, and Donnchad. Such grants appear to have been part of a coordinated campaign of the English and Scottish kings to gain authority over outlying territories where royal influence was limited.
