There were two men named S. W. Kennemer (Kenimer, Kennemore, Kemermer) from Conway County whose records seem to have been intermixed in both the 36th and 21st Arkansas Regiments -- Silas W. and Samuel W. -- both of whom moved to Alabama after the war.
Silas Wilaby Kennemer [1831-1890] is buried in Madison County, Alabama. Samuel W. Kennemer [1845-1920] is buried in Jackson County, Alabama.
Somewhere along the line, someone ordered VA tombstones and erroneously mixed up the service of the two men. As best as I can make out, Silas W. served in the 21st Arkansas, and Samuel W. served in the 36th Arkansas.
