Czesc Jurek,
if they had no farmers, I would expect these villages to at least be listed in the lost Herrschaft section – but apparently they were not. This can be seen from the list of villages that the Kataster originally contained: ZOA Opava 1191-87
I also missed some other villages of the Amt Rothschloss except Rothschloss itself and Tiefensee.
For me it remains mysterious.
Pozdrawiam
Viktor
