You seem to know a lot about the region. My great great grandfather Anton Haimann (Sometimes written Antal Haymann) was born in Mokrin Feb 23, 1866 to Simon Haymann and Terez Libozky. I was planning on asking if it was possible to get a birth record. FYI They were Roman Catholics.
Do you know if such church records are available or even accessible? Is it worth contacting him?
