The first burial appears to be that of the Thompson children, Effie and Francis, according to a tombstone transcription. However, there is a government military marker for a J.W. Payne, who died 10 July 1866. It is possible the date on the marker is wrong and it is also possible Payne's body was moved into the cemetery when it opened. He certainly was not buried in Spillman in 1866, when the county was sparsely populated and no cemeteries had been established.
Spillman is well-maintained and caretakers have taken the time and trouble to identify the unmarked graves. A homemade marker has been placed on each of those graves, with the name of the deceased engraved in the stone.

Spillman Cemetery is located in Section 30 of Cedron Township. The cemetery was surveyed on 4 May 1939 but was in use much earlier, of course.
