I read through the names you mentioned and have no connection by name. The Schoepfs I know came from Germany to Clayton, IA and then moved on to South Dakota. John Carl Schoepf married Augusta Samp in Clayton, IA. John had a brother named Charles (b. 1874 and d. 1963 Iowa) and a sister Flora or Fiona (b. 1867) and married to John Trail. I have no other records of these individuals but would like to know more about them.
