Olof Björnsson, Munsöätten - Dronning Helena av Skövde is Olof Björnsson, Munsöätten's third great granddaughter? Sources?

I am also trying to solve this line. I have uploaded a pedigree chart from wikitree to the media tab, hoping it may help. The tree shows Olof (Olaf) Björnsson and Ingeborg (Thrandsdotter) Thrandsdatter - married about 0920 in Scandiavia, have two children - Gyrid Olafsdottir and Styrbjörn Starke Olofsson. Maybe, this will fill the gap.

UPDATE: I solved the missing pieces of NN Obobrit and N Obobrit, with 2 sources for each. View my tree to see them.

The Obotrites (Latin: Obotriti, Abodritorum,Abodritos…) or Obodrites, also spelled Abodrites (German: Abodriten), were a confederation of medieval West Slavic tribes within the territory of modern Mecklenburg and Holstein in northern Germany.

https://en.wikipedia.org/wiki/Obotrites

I guess someone made a name out of it, but surely, who was named Obobrit?

Then there is a mistake in this profile also, Olof Björnsson comparing the about me in English with Swedish, suggest that someone have made a mistake.

List
Erik Björnsson, King of the Swedes
his son Björn på Håga, Sveakung
his son Olof Björnsson

There are two different Björn Eriksson, lived ca.100 years apart, both had a son named Olof
1 https://en.wikipedia.org/wiki/Bj%C3%B6rn_at_Haugi
2 https://en.wikipedia.org/wiki/Bj%C3%B6rn_Eriksson

Someone have taken this Olof Björnsson and given him the info in the about me section for the younger Björn Eriksson instead from the older Björn på Håga.

his brother
Eric the Victorious, king of Sweden

Glen Stephen Poland what do you mean View my tree to see them.?

Private User i think Dronning Helena Torildsdotter Blot-Sven, av Skövde and her parent's profiles are reasonable but :

Sigtorn? Prince Ingvar of Sweden?
N.N. Obobrit
N Obobrit

are inventions in an attempt to link Helena to Olof Björnsson, Munsöätten. Whether they are inventions from the middle-ages, 19th century or 2019 shouldn't matter.

Shall we delete them? As Ulf says Obobrit isn't even a name.

https://youtu.be/5cEK1OLhUKQ Eric the Victorious, king of Sweden should be reattached to his links back to the Munsöätten. In that way, people do not need to fabricate lines.

Can anyone validate this line (Alex):

Langfeðgatal is one of the better source for the the claim that Björn Eriksson is the father of Erik Segersäll, (the victorius).

https://en.wikipedia.org/wiki/Langfe%C3%B0gatal

Tis is the correct list according to Langfeðgatal where the correct sons to their fathers is in correct order.

Ragnar Lodbrok
Björn Järnsida
Erik Refilsson
Emund Refilsson
Erik Emundsson
Björn Eriksson
Erik Segersäll
Olof Sjökonung

Glen Stephen Poland Wikipedia and Wikitree are not sources.

Maureen Ellen Murphy No, if for no other reason than it starts with Ragnar.

Both "Obobrits" should be deleted. In my opinion.
