I apologize that in my previous post, in analyzing the information from the obituaries I forgot that your Ida Anna Bertha was Ernestine's niece, not her sister, so if Anna Baschke was Ernestine's sister, then she is not the person you're looking for.

By the way, Ernestine TOLZMAN Kohls Buhr's entry in the 1925 IA State Census gives WESTFALL as her mother Louise's maiden name.
