Thrúd.
Thrúd, more commmonly known as Þrúðr (Old Norse for "strength"), sometimes anglicized as Thrud, is a daughter of the thunder god Thor and the goddess Sif in Norse mythology. Thrúd is also one of the valkyries who serve ale to the einherjar in Valhalla.
In the lore, Thrúd is named as Thor’s daughter in Skáldskaparmál 4. She may also have been sought out as a bride in the Alvíssmál. This last source shows Thor winning a battle of wits against Alvis, a clever dwarf who came to him to claim his daughter in marriage. Thor keeps the unwanted suitor busy answering his questions until the sun rises and turns Alvis to stone. While the source does not name Thrúd specifically, it is not unlikely that she was the daughter Thor protected so vigilantly.
