One problem with Dwyer and Lingenfelter is the lack of documentation about their notes on John A Stone, Old Put.

A list of burials in Greenwood Cemetery, CA, includes John A. Stone, died 23 Jan.?? (no year given), and the remark AKA Joe Borners and born Pike County, Missouri.
Seemingly there is no year date on the marker or cemetery records are lacking. An investigator could not find who maintains the cemetery(2004).
Greenwood no longer exists except for the cemetery, estab. 1852.
