Budlungs :
Budli the sea-king settled down in Saxland. He was father of Attil (Attill), father of Vífil (Vífill), father of Læfi, father of Budli. This second Budli was father of Sörli (Sǫrli) or Serli, of Atli, and of Brynhild. Brynhild was mother of Áslaug, ancestress of Harald Fairhair as described in the previous Lofdungs discussion.
Atli is a legendary version of Attila the Hun and the name Budli comes from Bleda who was the historical Attila's elder brother. The name Sörli is given to a brother of Atli only in this text. But in the eddic poem Atlamál hin grœnlenzku (stanza 50), Atli declares that he was one of four living brothers when his father Budli died and that half of them are now dead, slain by his wife Gudrún. In the German Nibelungenlied Attila is called Etzel and said to be son of Botelung, obviously Budlung interpreted as a name. In this account Etzel has a younger brother named Bloedelin who was slain by Dancwart, Hagen's brother. Blowdelin is probably another memory of the historical Bleda. The eddic poem Oddrúnargrátr tells of Atli's sister Oddrún and her forbidden love affair with Gunnar, which was, according to this poem, one of the motivations for Atli's later treachery. Oddrún is also mentioned in Sigurðarkviða, in the prose introduction to Dráp Niflunga, and in the Völsunga saga
