Greetings all:

I'm searching for the grave site of my Great Grand Father Adolph Franklin "Frank" Hoover
Born: 30 Oct 1882 in Eastland County, Texas
Died: between Sept 1918 and 1920 in prob Strawn,Texas

In 1918 he was alive and registered for the WWI draft in Palo Pinto, Texas, living in Strawn, Palo Pinto Co. Tx
In the 1920 Census his wife Winnie Elizabeth (Browning) Hoover is listed as a widow

Frank was a widow his self before re-marrying as his first wife Julia Emmeline (Lang) Hoover died 1910 in Brownwood, Brown Co.,Texas

I feel that Frank is buried in the Unmarked (except for large native sandstone no name) Adult Grave in Bollinger Cemetery, Eastland Co.,Texas
But i can find no "paperwork" proof of this
Both of Frank's parents Augustus B Hoover and Louisa "Livisa" (Pape) Hoover are buried there in the Bollinger Cemetery

I looking for any paperwork proof, or oral statement of anyone who knows for sure

Thank You in advance for any help with this.

Michael Hoover
