Recently i've come across this name Neuhäuser from looking in the Czech archives.
Because the Old Script writhing is so hard to read, I am not 100% certain about the facts.
But I think my Grandfathers mother was a Neuhäuser (Maria Theresia) married Wenzel Motz. My grandfather grew up in Ketten (Chotyne) and later lived in Grottau (Hradek nad Nisou).
I'd love to know more.
