*Please note that I am very aware that this is comic book artwork and that Sif is known for her blonde hair and in the comics she has dark hair. I really liked the artwork and love the comic so I went with this picture.
Thor
Thor is the red-haired and bearded Norse god of thunder.
Thor was appealed to for protection. Miniature replicas of Mjöllnir, the weapon of Thor, became a defiant symbol of Norse paganism during the Christianization of Scandinavia.
Thor is the son of Odin and the giantess Jörd (the Earth), who may or may not be the same as Fjörgyn, who is also said to be his mother. His wife is called Sif; little is known of her except that she has golden hair, which was cut off by Loki. With his mistress, the giantess Járnsaxa, Thor had two sons, Móði and Magni. With Sif he had his daughter Thrud.
The euhemeristic prologue of the Prose Edda also indicates he has a son by Sif named Lóriði, along with an additional 17 generations of descendants, but the prologue was meant to give a plausible explanation on how the Aesir came to be worshipped even though they were more like giants than gods. Thor also has a stepson called Ullr who is a son of Sif. Skáldskaparmál mentions a figure named Hlóra who was Thor's foster mother, corresponding to Lora or Glora from Snorri Sturluson's prologue, although no additional information concerning her is provided in the book.
Thor owns a short-handled hammer, Mjöllnir, which, when thrown at a target, returns magically to its owner. His Mjöllnir also has the power to throw lightning bolts. To wield Mjöllnir, Thor wears the belt Megingjord, which boosts the wearer's strength and a pair of special iron gloves, Járngreipr, to lift the hammer. Mjöllnir is also his main weapon when fighting giants. The uniquely shaped symbol subsequently became a very popular ornament during the Viking Age and has since become an iconic symbol of Germanic paganism
I could honestly go on and on about Thor, he is one of my favorite gods of all time and could get lost searching up all information on him but then what would you guys add so I'm going to leave it at this.
Sif
In Norse mythology, Sif is a goddess associated with the earth with famously golden hair, and the wife of the god Thor. Sif is attested in the Poetic Edda, compiled in the 13th century from earlier traditional sources, and the Prose Edda, written in the 13th century by Snorri Sturluson. In both sources, Sif is the wife of the god Thor and is known for her golden hair.
In the Prose Edda, Sif is named as the mother of the god Ullr (whose father's name is not given) and is told to have once had her hair shorn by Loki. Thor forces Loki to have a golden headpiece made for Sif, resulting in not only Sif's golden tresses but also five other objects for other gods.
Scholars have proposed that Sif's hair may represent fields of golden wheat and that she may be associated with fertility, family, wedlock and/or that she is connected to rowan.
