I think WikiTree just reached 17 million profiles.
Sometimes it seems everyone wants a viking in their tree and since there are (still) not many Scandinavians members of WikiTree compared to Americans I guess profiles like this one have not been questioned.
Norway don't have a project started yet, Denmark and Sweden exists and Finland is just starting up a project right now. Hopefully, with more Scandinavian members, perhaps profiles like these will get some attention from people who might know what saga/legend it was taken from. Or if it really was a real person, and if so, who the profile really refers to.
Because there is no "Esmen of Norway" that I can find in any search I tried for it. And a name like Svenwoman is just not a Nordic name at all, that is (at the best) some kind of invented/translated English name. So most probably this is just an inventive fantasy by someone wanting to connect to some royalty and then it has found it's way around multiple genealogy sites and became "truth".
If you really believe this could be an ancestor you should try to back it up with real published sources, then it would get some credability and we would be able to discuss it.
Edit:
The information on the profile for "King Hacken I Grandt aka King of East Angles"
https://www.wikitree.com/wiki/Grandt-7 indicates it's a scam from 1710 connecting back to the norse god Odin. I will add the tags for EuroAristo and pre-1500 to this question so people following those tags will find this question.
