I just uploaded a bunch more detail to the Ancestry page of this site. It’s only a bare beginning, just a list of names with some basic info and a lot of Wikipedia links. This ancestry traces back to the Viking Sagas, and the Yngling dynasty, which is the oldest known Scandanavian dynasty. this goes back through Snorri Sturluson’s writing, and they are mentioned in Beowulf.
This ancestry walks an intriguing line between history and mythology. I look forward to diving in more deeply and adding as much info as I can find. This will likely be a project that unfolds over many years.
