'Lynette' suggests that John's date of death is not 1970, but May 3, 1952! A photo of a memorial confirming this would be helpful. Lynette also gives a birth date for John which confirms the September 1883 date in the 1900 census.
Looking for further information.
This virtual memorial moved from Greenwood to Lincoln Memorial Park on October 16, 2013. Hope to resolve differences and consolidate the two memorials at this location into one.
