The Orkneying saga does not speak at all of Nór's descendants, but introduces instead a figure named Halfdan the Old as the son of Sveidi (Sveiði) the Sea-king, who is called Svadi (Svaði) in the Ættartolur. Sveidi/Svadi in both texts was son of Heiti, son of Gór who was Nór's brother.
This second Halfdan the Old is father of Jarl Ívar of the Uplands who married a daughter of a certain Eistein and so became father of Eystein the Clatterer (Eysteinn Glumra)
