A community began to develop near this site during the 1870s and was known by several names, including Possum Trot, Prickly Pear, and Ettowa before a post office was established under the name Saturn in 1902. Hugh and Elizabeth (Burleson) McMillan sold two acres at this site to the Good Hope Primitive Baptist Church for a cemetery in 1882. The site was already the resting place of their daughter Martha McMillan Dubose, who died in 1880. The burial ground continued to be used by the McMillan and Dubose families, as well as other members of the Saturn community. A cemetery association was formed in 1974 to oversee the operations of the cemetery, which serves as a reminder of early Gonzales county pioneers.
