Thor and Hildólfr Hermóðr, Sigi Skjöldr and Ítreksjóð Heimdallr, Sæmingr Höðr and Bragi Sigi is ancestor of the Volsungs. Skjöld is ancestor of the Danish Skjölding dynasty, Yngvi of the Swedish Ynglings. Sæming is ancestor of a line of Norwegian kings. All appear in Snorri's pseudo-historical Prologue to the Prose Edda as sons of Odin and founders of these various lineages, perhaps all thought to be sons of Odin begotten on mortal women. A Faroese ballad recorded in 1840 names Odin's son as Veraldur, this Veraldur being understood as another name of Frö, that is of Frey. The name Hildolf appears in the eddic poem Hárbardsljód applied by the ferryman Harbard to his supposed master, but Harbard is actually Odin in disguise and there is no clear reference here to a son of Odin. The otherwise unrecorded Itreks-jod "offspring of Ítrekr" may be a reference to any of the sons of Odin, Ít-rekr "glorious ruler" being a name of Odin. Meili also appears in the eddic poem Hárbardsljód, where Thor calls himself Odin's son, Meili's brother, and Magni's father. In Snorri's Gylfaginning, Ali is only another name for Vali, and Nep is the father of Baldur's wife Nanna. If this list is correct in giving Odin a son named Nep, and if that Nep is identical to the father of Nanna mentioned by Snorri, then Nanna would also be Baldur's niece. But marriage between uncle and niece, though common in many cultures, does not normally appear in old Scandinavian literature. Týr, Höd, and Bragi are conspicuously absent from this list, one reason to believe it is not from Snorri's hand. Some manuscripts have a variant version of the list which adds Höd and Bragi to the end and replaces Yngvi-Frey with an otherwise unknown Ölldner or Ölner. This may be an attempt to bring the list into accord with Snorri, even though it still lacks Týr. Some manuscripts add additional names of sons of Odin which are otherwise unknown: "Ennelang, Eindride, Bior, Hlodide, Hardveor, Sönnöng, Vinthior, Rymur." Founders of dynasties The prologue to Snorri's Edda and the alternative list discussed above both include the following: Sigi. He was made the ancestor of the Völsung lineage (see Völsunga saga), who were Burgundian kings according to Snorri. Skjöld. In Snorri's Ynglinga Saga in the Heimskringla, Skjöld's wife is the goddess Gefjön and the same account occurs in most, but not all, manuscripts
