It is conceivable that Rǫgnvaldr's marriage was undertaken before 1210, perhaps not long after 1200 considering the fact that Guðrøðr Dond—a product of this union—was an adult by 1223 and had fathered at least one son by this date. Óláfr's marriage to Lauon may have taken place in 1216. The binding of Rǫgnvaldr and Óláfr to Clann Somhairle wives could well have been orchestrated in an effort to patch up relations between the Crovan dynasty and Clann Somhairle, neighbouring kindreds that had bitterly contested the kingship of the Isles for about sixty years.
