The marriage of "Eithne, daughter of King Kjarval of Ireland" and Hlodvir Thorfinnsson, Earl of Orkney is reported in the Orkneyinga saga and Earl Sigurd the Stout, who was killed at the battle of Clontarf is called their son.
Their marriage did not produce a male heir, though it did produce a daughter, Ingeborg Eriksdottir of Norway, who, having firstly been engaged to Jon II, Earl of Orkney, married Valdemar Magnusson of Sweden, Duke of Finland, in 1312.
He was responsible - in a bizarre posthumous incident - for the death of Sigurd the Mighty, Earl of Orkney.
