Per "Heard County, Georgia Cemeteries," c.1977 by Lynda S. Eller, pg. 83-84;
Catherine is listed with the burials for the BEVIS Cemetery, which also has several other May burials. It was surveyed on Feb 8, 1976.
The Bevis Cemetery is listed with the cemeteries for GMD 788 - Franklin, GA. It looks like it is on the east side of Hwy 27 as it heads northeast out of Franklin.
Maybe someone else can jump in with more specific directions.
Good Luck,
