Actually, now that I look in more detail at the former borders of Saxe-Altenburg, both of those Waltersdorfs are within the bounds of that state (Saxe-Altenburg was actually divided into two, with an eastern part and a western part, divided by Gera in the middle). And both are about 25 km from Gera, so we can't really tell which one August came from. Sigh.
