It is possible that Lochlann's foster son is identical to a similarly named individual, a certain "", who attested a quitclaim between Llywelyn ap Gruffudd and Ralph de Mortimer, in about 1241. It is uncertain what compelled Lochlann to flee his sovereign, and it is uncertain why he chose Wales as his destination. The Crovan dynasty certainly had diplomatic and familial connections with the Welsh. One possibility is that the account of Lochlann's flight reveals that he attempted to replace Óláfr's son, Haraldr, with another son. If the chronicle is incorrect in its account of the foster-son's maritime demise, and he is indeed identical to the like-named Manx prince attested in Wales, this individual's activities outwith the realm of his ancestors may have been a consequence of strife following Óláfr's death and Haraldr's accession. Haraldr's young age at the time, and the fact that he had a potential rival in the person of his like-named cousin, Haraldr Guðrøðarson, could indicate that Haraldr had been designated as successor during his father's lifetime.
