according to "laxdæla saga", olaf was a precocious child, and could speak and walk perfectly by the age of two. one day hoskuld discovered olaf's mother speaking to her son; she was not, in fact, mute. when he confronted her she told him that she was an irish princess named melkorka carried off in a viking raid, and that her father was an irish king named "myrkjartan" (muirchertach). shortly thereafter squabbling between jorunn and melkorka forced hoskuld to move his concubine and his son by her to a different farm, which thereafter was known as melkorkustaðir.
