Dear Pat,
Do you have any information on Barbra Schoens' family that came from Darmstadt? My G_Grandfather Henry SChoens' family came from there. He adventually rooted in Indianapolis.I know one brother was Gustuv Schoen Father of Karl Louis Schoen,aviator killed in WWI. They also had settled in Cape G., Missouri. Barbara Schoen I believe was his sister, so maybe she is the one you are looking for in Randolph County.
Please e-mail back and let me know if this ties in with your branch. Thanks-Terri
