in a document I found about a relative, I came upon the following:
translation: wife from Schalkavas, Yugoslavia
Has anyone ever heard of a village by that name or a similar sounding one?
I can't find anything when doing a Google search, not even a "Did you mean..." is coming up, which is rather strange... https://www.google.com/search?q="Schalkavas"
It might or might not be a Danube-Swabian settlement, but it looks like a Germanised spelling of a Yugoslavian name, and it doesn't seem likely to me that they invented one just for this document, so I think it's more probable that it was a town with enough German settlers to have a German name.
Hoping anyone has an idea...
