I would very much like to get a copy of the Knittel book you spoke of. My family appears to have immigrated from Alsace Lorraine, France. Sometime after 1852. My great-grandfather was Francis Joseph Knittel. His son was William Leo Knittel. My father was Louis Omar Knittel. Most of my family ended up in Mooreland Oklahoma, but Francis Joseph Knittel was married in Iowa. Thanks for any help you can give me! Bonnie Knittel Roloff Modesto, Calif.
