I too am researching Samuel Bachtel, my great-great grandfather who was married to my great-great grandmother, Mary Rowland. Some additional information about Samuel is below:
1. Samuel was married three times. My great-aunt thought wife #1 was Elizabeth Graybeal (or Grabie), wife #2 was Abigail BAUKUS/BACKUS/BACHUS, and wife #3 was my great-great grandmother, Mary Rowland (sometimes written as Roland or Rolland) Goodenberger).
2. Samuel and Abigail had a son named Jabob I. Bachtel, who married Aletha Triplett.
3. Samuel had one brother, David, and several half-brothers (Same and Jake of Akron, Ohio, and John from Canton, Ohio) and half-sisters. I don't know the names of the half-sisters or if they are related paternally or maternally.
