Thank you so much, Ralph, for replying with your details about the funeral home records.It is unfortunate that the funeral home records do not show the cemetery by a name.
On Joseph Reams' death certificate the informant was Mrs. Jesse Draper. I note on Find A Grave, a Jesse B. Draper buried at Maple Grove (with tombstone photograph)and his wife was Ella Shirk Draper. Jesse's mother is shown as Ellen E. Reams Draper. His father was Joshua Draper. All buried in Maple Grove Cemetery with gravestone photographs.
The death certificates and obituaries tell us that George, Rosana (AKA Rosanna) and Joseph died single, it certainly is possible that they were buried in unmarked graves. Joseph Reams' obituary shows that he was survived by several nieces and nephews. They all appear to be buried on a lot or lots under someone else's name. Perhaps under one of the Draper names. Yes, it is confusing with Ream/Reams/Reames used for them on different records.
