You forgot the rest of the list of the in Scandinavia commonly known Skilfinga-dynasty; Yngvar, Eystein, Adils, Ottar, etc back to Agne (around y. 400) :) They have burial mounds with their names attached to them and figure in the Sagas, and in Beowulf.
These are saga material but also archealogical and partially proved, the debate about who's historical is still going on. Beyond that there is certain unvalidated proof that the Skilfinga has connections with the Amals ( Alareik = a relative in king Alrek) of the Gothic migration on the continent (that figures in for example the Hervarar Saga), and could also be the latter dynasty of the even older partly historical Ynglinga-dynasty overruling an elder culture, and starting with Yngve/(Frey)and his children the centuries after year 0, and the stories of Odin and other dynasties related to him. :) There is commonly known proof and serious debates about this (not the Odin part), but either way the first couple of names are certainly validated and could be added. :)
