Hello Mrs. Buck Smith,
your ancestor was born as Hermann Hinrich Wachtendorf in Ollen, parish Berne. You can find him with his parents and siblings on our page www.auswanderer-oldenburg.de. The birth place of his wife seems to be Schönebeck (Schoenebeck).
A copy of this I sent to Mr. Wragge who works on the parish records of Berne and Warfleth.
Best regards,
Gunter Jüchter
