I have started to look into the Reed/Epker Families from Adams County Illinois and Hannibal MO. I am Becky Crane's 1st cousin. She has had her hands full lately. Her Mother was My Father's youngest Sister. I met Jettie Probasco on several occassions as a small child and have a newspaper notice of the death of the first child of John and Jetty's. I also have some other newspaper clippings that my Grandmother Henriette REED Clark had that I found recently in my Dad's things.My oldest brother Richard Clark Jr has done the family history on the Clarks but does not seem to know to much on the other side.
John William Reed was born in Illinois. His Father William M. was born in England and his mother was a Harriet Miller or Millar.
As far as the Epkers go I have a German Ancestry expert helping me with this part of the project. I have both a maiden name and married name for Katrina.
Be careful with some of the information you get from the LDS Family Libraries. Finding anything there needs to be treated as a pointer only until we have 2 hard pieces of evidence.
I don't know if any of this helps.
