I am taking digital pictures of St. John's cemetery and listing them online at find-a-grave. I have not found any Hafner or Klotz up to now. I do not have the listing of the cemetery, but I do live in Pine Grove area. If I know what section the graves are in, I can get the pictures for you. This is a very large cemetery. However, it is too cold right now to get any pictures. As soon as it warms up and I have time I will resume my project. Have you tried to contact the church?
