One of my maternal grandmother’s brothers was very interested in genealogy, i.e. in our family’s history and bloodlines. He travelled a lot and did decades of research.
He led our line back to king Harald Hårfagre (Harold Fairhair), born ca. 850 and died ca. 932. King Harald is remembered as the first king of Norway.
King Harald Hårfagre went on a quest to gather all of (southern) Norway into one kingdom, and he swore not to cut his hair until his quest was finished.
The story as I was told it as a child, said that the king travelled over the Dovre mountain region, on his way to Trøndelag, where he stopped and rested at a farm. There the king fell in love with a woman, and he stayed with her until their child was born. Then the woman fell ill, and the king sat by her bed an mourned. Eventually she died. The king left the child to be reared with the farmer and his wife, and continued on his quest. This child became one of my maternal grandmother’s family’s foremothers or forefathers (I can’t remember which).
In the “official” story written down a few centuries later by Christians, the woman at the Dovre farm was turned into a witch, who cast a spell on king Harald to make him stop on his quest. The king sat by her sick bed, and when she died, her corpse burst and toads and snakes crawled out of it. This was a sure sign that she was evil.
(The same narrative technique was used in the story about king Olaf Trygvasson. He stopped at a village where they had a large wooden figure of Thor. It was said that he split this statue in two and snakes/rats/toads crawled out, a sure sign that it was a symbol of evil.)
Another interesting thing: king Harald Hårfagre’s father was Halvdan Svarte (Halfdan the Black), and his family descended from the Ynglingeætt, the Ynglinge royal family line. The progenitor of the Ynglingeætt is said to be Yngvi-Freyr.
So Freyr is my many-many-many times great grandfather.
