I also am researching the Kadletz family. Barbara Kadletz is my 3rd great grandmother. Barbara's son John Jisa is my 2nd great grandfather which I believe is Anna Jisa's brother. I have Anna (Jisa) Zelenka's obituary if you would like. I also have Barbara (Kadletz) Jisa and Albert Jisa's death certificate. I do not know alot about Katherine (Schweiner) Kadletz. I do have information on thier immigration. I live 20 miles south of Kewaunee and am very familiar with the Pilsen of which they resided. I also have some photos.
I'd be glad to share any information with you.
