I don't have an answer to your question about Christian Ditzler. However, the Charles Sumner Ditzler you mention may also be my great-grandfather. I believe that my grandfather was named Charles Sumner Ditzler in Muskogee, OK. He died when my father, Charles Hugh Ditzler, was about 8 or 10 years old. After being stationed in Topeka, Kansas during WWII, my dad met my mother and settled in Topeka, where my 3 brothers and I were born and raised. My father died 12 years ago. At 29, I moved to San Francisco and have been in the Bay Area for another 29 years. I will speak to my mother (Topeka), to confirm my grandfather's name.
