but we use the most used and well known name and this is Wencke Myhre Wenche is still listed as alternative name

Most used where? Most well know where? Back up these claims with hard data.

Imdb correctly uses Wenche, as this site also should to maintain some semblance of professionalism.

when you look at the appearences in her profile you can see that 90% uses the name Wencke Myhre

Sure, she uses that name in german speaking countries, so all those tv episodes do add up. But this site should not allow such regionalisms to prevail as the standard spelling of the name (which is why neither Imdb nor Wikipedia does).

Found this in the guidelines: "When a person uses many names simultaneously and alternatively, choosing a primary name is usually a judgment call based on a few factors: Is there a name they are most often credited as? Which name is used on their official website and social accounts? Which name is used on their agent or union's website? Which name are the other major websites are using?"

Social: https://www.instagram.com/wenchemyhre_official/ Agent: https://kjentfolk.no/tjenester/1575/ And other major sites we already know. In this case, Wenche wins 3-1.

So I let the decision to another moderator now

Agreed. Name changed.
