Quick Q about the origin of a name?

Which country would the name Sonja Danner belong too? I’m trying to figure this out but it is mildly confusing.

Any ideas? It sounds Germanic, but I can’t be sure…

BTW it is a female name.

I just searched the name in Google and found several hits for someone (possibly more than one someones) in Austria named Sonja Danner.

Hope this helps.
