Those records are too recent to be online. The books probably still are at some municipal office. Since you are a direct descendant, you should be able to obtain a copy of the records after you give them documents proving your relationship and pay a fee. But frankly, I don´t know if people at that office will be able to communicate in English and if this can be arranged by email. You´ll have to try, I guess :-)
As for the records, I´d try to look for them at Nový Kostel, Skalná or perhaps Cheb.
