His descendants Grim, Audulf and Gorm (I) the Childless also ruled in Jutland. Gorm I adopted the foundling Knud, whose son Gorm II was the foster father of Hardeknud I, ancestor of the later Danish kings. The saga refers to names found in Anglo-Saxon royal genealogies, ancestors of Ecgberht, King of Wessex. Ad catalogum regum Sveciæ annotanda (Skjöldunga saga) The Skjöldunga saga tells that Sigurd Ring was married to Alfhild, the daughter of king Alf of Alfheim, and their son was Ragnar Lodbrok.

Rather, he is the son of a Norwegian chief Sigurd and the maternal grandson of the historical King Götrik (i.e. Gudfred, d. 810).
