Wow, this is interesting. I'm not sure about Bertha but there was an Emma Schuebel (born 1860) who married Henry Baltz and had two sons with him, John Baltz and William Herman Baltz (my mother's father.) Either Henry Baltz died or Emma divorced him because Emma Schuebel Baltz later married William G. Breuninger (born 1863-- my mother's grandfather on the maternal side.) Yes, my maternal great grandfather married my paternal great grandmother! It makes you dizzy, doesn't it? I don't know of any Charles in the family. Hope this helps. Keep in touch. Can you see my Family tree? My first cousin, Roberta Andrew Hewitt is always adding info to Ancestry.com so she may know more than I do.
