My grandfather's name is Russell Sylvanus Diefenderfer. His mother's name is Helen M. Diefenderfer. Her father's name is Sylvanus Diefenderfer, her mother's name is Maria. Sylvanus Diefenderfer's father is A. Diefenderfer.
It appears my grandfather may have been born out of wedlock then my great-grandmother married an Edelman. (The Edelman family lived next door to Sylvanus and Maria Diefenderfer).
Any help you can give in determining who "A. Diefenderfer" is would help in connecting us with the ancestry family tree.
