I think that it is important for people to realize that your cemetery listings are not necessarily complete. In other words, if there is no headstone, their relatives may still be buried in a cemetery. It is important to look for the written cemetery records.
I have two relatives in
Pine Bend Cemetery. However, they are not in your transcrptions. The reason I know they are buried in
Pine Bend Cemetery is because they are included in St. Luke's Episcopal Church
Records with the place of burial being
Pine Bend Cemetery.
