I have responded once before to your messages and seriously hope that you will contact me ASAP. Diane Graul, Richard's sister, I believe, lived with my grandmother (Emma Behnke/Schaefer) and step-grandfather (John Kochin) until she became an adult. Virgiline Schaefer is/was my father's sister. My father was Aloysius John Schaefer, Virgilene's younger brother. I may still have a way to reach Diane Graul (whose married name is now something else ???), and SHE may know more about Richard.
