Melkorka is the name given in Landnámabók and Laxdæla saga for the Irish mother of the Icelandic goði Ólafr Höskuldsson. It is possible that her name represents the Gaelic Mael Curcaig. According to Laxdæla saga, Höskuldr purchased Melkorka, who he believed to be a selective mute thrall-woman, from a Rus' merchant on Brännöyar while on a trading expedition to Norway, and made her his concubine while away from his wife Jórunn Bjarnadóttir. When Höskuldr returned home to Iceland, he took her with him. Despite Jórunn's irritation, the concubine was accepted into Höskuldr's household, though he remained faithful to Jórunn while in Iceland. The following winter the concubine gave birth to a son, to whom they gave the name Ólafr after Höskuldr's uncle, Olaf Feilan, who had recently died.Landnámabók mentions that Höskuldr and Melkorka had another son, Helgi, but he does not appear in Laxdæla. According to Laxdæla saga, Ólafr was a precocious child, and could speak and walk perfectly by the age of two. One day Höskuldr discovered Ólafr'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 Jórunn and Melkorka forced Höskuldr to move his concubine and his son by her to a different farm, which thereafter was known as Melkorkustaðir. The fact that there is another site known by this name, at Borgarfordur, could indicate that Melkorka's name is not Gaelic in origin, but is instead derived from a name composed of the elements melr ("gravel hillock") and korka ("wasting away"). Around 956, Ólafr, at Melkorka's urging, decided to go abroad to seek his fortune. Melkorka taught Ólafr Irish Gaelic and urged him to visit her family. Höskuldr was opposed to the expedition and would not provide trade wares, and the property of Ólafr's foster-father Þórðr was mostly in immobile goods and land. In part to arrange financing for his expedition, his mother Melkorka married Þorbjörn skrjúpur ("the Feeble"), a farmer who had previously assisted her in the management of Melkorkustaðir. Melkorka and Þorbjörn had a son named Lambi.
