=''Sögubrot''=
Sögubrot tells that he married the fugitive princess Auðr the Deep-Minded, the daughter of Ivar Vidfamne, without the consent of her father king Ivar Vidfamne, who soon departed to punish his daughter. He died en route, however, and so Ráðbarðr helped Auð's son Harald Wartooth claim his maternal grandfather's possessions in Sweden and Denmark.[https://web.archive.org/web/20100908081803/http://www.oe.eclipse.co.uk/nom/Fragment.htm Fragment of a Saga about Certain Early Kings in Denmark and Sweden], English translation by Peter Tunstall
