Various gods and men appear as Sons of Odin or Sons of Wodan/Wotan or Sons of Woden in old Old Norse and Old High German and Old English texts.
Four gods, Thor, Baldr, Víðarr and Váli, are explicitly identified as sons of Odin in the Eddic poems, in the skaldic poems, in Saxo Grammaticus' Gesta Danorum, and in the Gylfaginning section of Snorri Sturluson's Prose Edda. But silence on the matter does not indicate that other gods whose parentage is not mentioned in these works might not also be sons of Odin.
In various kennings Snorri also describes Heimdallr, Bragi, Týr and Höðr as sons of Odin, information that appears nowhere else in the Edda.
For Heimdallr there is no variant account of his father. The same may not be true for Bragi if Bragi is taken to be the skaldic poet Bragi Boddason made into a god. But Týr, according to the Eddic poem Hymiskvida, was son of the giant Hymir rather than a son of Odin. As to Höd, outside of the single statement in the kennings, Snorri makes no mention that Höd is Baldr's brother or Odin's son, though one might expect that to be emphasized. In Saxo's version of the death of Baldr, Höd, whom Saxo calls Høtherus, is a mortal and in no way related to Saxo's demi-god Baldur.
Hermód appears in Snorri's Gylfaginning as the messenger sent by Odin to Hel to seek to bargain for Baldr's release. He is called "son" of Odin in most manuscripts, but in the Codex Regius version—the Codex Regius is normally considered the best manuscript—Hermód is called sveinn Óðins 'Odin's boy', which might mean Odin's son but in the context is as likely to mean Odin's servant. However, when Hermód arrives in Hel's hall, Snorri calls Baldur his brother. To confuse matters other texts know of a mortal hero named Hermód or Heremod.
