[2] While nothing in particular is told about the reign of Guðröðr, his brother Halfdan supposedly married an Anglian lady called Moald and obtained the lordship over Northumbria.
[5] An episode in the fragmentary saga Sögubrot draws a parallel between Guðröðr and "Heimdall, who was the most foolish of the Aesir, though he was bad to [Ivar Vidfamne]",[6] implying that he was compared unfavourably with his highly praised brother Halfdan.
Hervarar saga and Hversu Noregr byggdist give more information about his brother Halfdan the Valiant and his son Ivar Vidfamne, and by implication about Guðröðr himself.
Hervarar saga provides the information that Halfdan's mother was Hild, the daughter of the Gothic king Heiðrekr Ulfhamr, the son of Angantyr who defeated the Huns.
The Vestfold ruler Gudrød the Hunter (9th century) met a similar fate at the hands of his queen Åsa Haraldsdottir of Agder, who ordered a servant to murder the king as revenge for the death of her father.
