 Upon Óláfr 's return the chronicle says that Rögnvaldr welcomed him back and had him marry Lauon , the daughter of a certain nobleman from Kintyre , who was also the sister of his own wife . The precise identification of the father @-@ in @-@ law of Óláfr and Rögnvaldr is uncertain , but he may have been a member of Clann Somairle ; possibly Ragnall mac Somairle , or his son Ruaidrí , who are both styled Lord of Kintyre in documents contemporaneous to their reigns . The chronicle states that Rögnvaldr then gave Lewis back to Óláfr , where the newly @-@ weds proceeded to live until the arrival of Reginald , Bishop of the Isles ( d. c . 1226 ) , sometime later . According to the chronicle the bishop disapproved of Óláfr 's marriage , as Óláfr had formerly had a concubine who was a cousin of Lauon . A synod was then assembled and the chronicle records that the marriage was nullified . Although at first glance the marriage appears to have been doomed , as it was deemed " as being within prohibited degree of kinship " , it may be that this was merely a convenient excuse , and that the contention between the half @-@ brothers may have played a part in its demise . It is also possible that Bishop Reginald may have released Óláfr from an arranged marriage which had been forced upon him ; the bishop and Óláfr appear to have been close , as the chronicle describes Bishop Reginald as a son of Óláfr 's sister , and notes that Óláfr was glad at his coming to Lewis . Furthermore , it was Bishop Reginald who annulled the marriage which Rögnvaldr had arranged for Óláfr . In fact , when the previous Bishop of the Isles died in 1217 , Bishop Reginald had vied with a rival candidate for the position — a certain Nicholas — and there is evidence to suggest that Reginald was supported by Óláfr , while Óláfr 's half @-@ brother Rögnvaldr supported the bid of Nicholas .
