There was a C.S. Jones in Company A of the Third Arkansas Cavalry. Company A was organized in Dallas County. If this is your ancestor then this may explain some of the confusion.

"The 3rd Arkansas Cavalry was organized at Little Rock on June 10, 1861, as the 1st (Borland’s) Battalion Arkansas Cavalry. On July 27, 1861, the battalion was mustered into Confederate service for one year, and on July 29 was reorganized as the 1st Regiment Arkansas Mounted Volunteers. On January 15, 1862, it was redesignated as the 3rd Regiment Arkansas Cavalry."
