Thanks, Tina! For some reason I didn't get an alert and am just seeing this message. I appreciate your information.
With the help of the Scioto County Chapter of the Ohio Genealogical Society, a Biars cousin, and a Milldale Road resident, I did locate the cemetery and have added information on Find a Grave. My traveling companion, who is a better climber than I, actually went to the cemetery and took some photos. Here is a list of names from those photos and a 1982 inventory done by Virgil and Marguerite Ramsey:
Pearlie Irena Webb, daughter of William and Weltha Webb; Corpl. William M. Rice; Lettie and Howard Presley; F. Neal, a baby; Edgar Fletcher; Goldie Sue Fletcher; (single name) Bocker; Rachel Walk; Denver Gearheart, an infant; John Phillip A. Biars (my great uncle) and his daughters Marion Jane and Opal; Infant Locher, son of P & M; Albert Locher, an infant, son of G & M; and Fred (no last name) who died in April (no other dates).
If anyone has pictures or further information about these folks, please let me know. You can reply here or by e-mailing me from one of the memorial pages.
