Which king of Yngling lived 515 - 530?
Yngling The Ynglings were the oldest known Scandinavian dynasty. It can refer to the clans of the Scylfings (Old Norse "Skilfingar"), the semi-legendary royal Swedish clan during the Age of Migrations, with kings such as Eadgils, Onela and Ohthere. When "Beowulf" and "Ynglingatal" were composed sometime in the eighth to tenth centuries, the respective scop and skald (poet) expected his audience to have a great deal of background information about these kings, which is shown in the allusiveness of the references.
Ingvar Yngvar Harra (or Ingvar) Proto-Norse *"Ingu-Hariz" (d. early 7th century) was the son of Östen and reclaimed the Swedish throne for the House of Yngling after the Swedes had rebelled against Sölvi.
