Looking for information on Thannheiser/Wagner/Kunze families in area of Patschkau kries Neisse in Ober Schlesien.
I am particularly interested in early 1800's to 1948 (pre-expulsion) on the Thannheiser side, especially WWI records that I can link to a known relative.
Some relatives are from the part of Schlesien that is now in Austria and a part now in the Czech Republic.
Any help you can provide is appreciated. Collaboration is welcome on these families.
