nefa ‘nephew’: As regent in Norway Knútr appointed Hákon Eiríksson, who was his sister’s son: Hákon’s father, Eiríkr jarl Hákonarson of Hlaðir (Lade), married Knútr’s sister Gyða. According to John of Worcester (Darlington and McGurk 1995-, II, 510-1), Hákon was also Knútr’s nephew-in-law, having married Gunnhildr, the daughter of another of Knútr’s sisters. However, Hákon died at sea in 1029 (or 1030, as recorded in ASC s. a.), at which point Óláfr Haraldsson chose to return from exile, leading to his death in battle at Stiklastaðir (Stiklestad).
