You're welcome Sunny.
I did not mean to suggest calling just to show you that surname STAUBER shows up in Czech Republic. I would recommend something like sending a letter to the surname holders in the ancestral location or vicinity of about 10 miles with a photo of an ancestor, if possible, or a small family tree and your e-mail address.
Going thru the church records should be helpful. http://www.mapy.cz/#x=13.008119&y=49.341571&z=12&...
