Hi:
Saw your entry on web.. I know you need more data than I have but I do think Wilhelm Keller, born June 1850 was in the war. A deceased cousin told me years ago he told her he was in the Prussian war 1870/71. That conversation would have taken place in the 1920's. He would have certainly been the right age. Have reason to believe he was born in Freystadt, known today as Kisielice. Any thoughts??
