Immediately after its account of Óláfr's marriage to Cairistíona, the chronicle details outright conflict between Óláfr and Rǫgnvaldr's family. The fact that this outbreak of violence is specifically dated to 1223 could indicate that it was Ruaidhrí's apparent downfall in Kintyre that led Óláfr to realign himself with Fearchar. By linking himself with Fearchar, Alexander's leading lieutenant in the north, it would appear that Óláfr recognised a regional shift in power, and therefore attempted to bind himself to a rising star in Scotland, and extract himself from any liability connected to Lauon's kin. Another apparent aftereffect of the Scots' invasion of Kintyre was the creation of the Clann Dubhghaill Lordship of Argyll, first evinced in 1225. If members of the Clann Dubhghaill branch of Clann Somhairle indeed began operating as agents of the Scottish Crown at about this time, it is possible that Óláfr—as a rival to ruler of a reformed Kingdom of the Isles—acted as an agent of Scottish interests as well. As such, Óláfr's marriage to Cairistíona may have ultimately stemmed from a Scottish desire to destabilise the Isles. If Lauon's father was indeed Ruaidhrí, it is possible that Óláfr compensated the latter for his marriage by granting him lands or protection in the Isles. It is also possible that Ruaidhrí's descendants—Clann Ruaidhrí—owed their later power in Garmoran and the Hebrides to Óláfr's patronage.
