Alexander Cemetery / This burial ground has served residents of southern Erath County since the late 1800s. At that time, the community of Alexander, platted by the Central Texas Railroad Company, was thriving. The community had received a post office in 1876, when it was named Harper's Mill (it was renamed Alexander in 1881), although settlers had lived in the area since before the Civil War. By the 1890s, Alexander had a number of businesses.

In the early 1880s, Confederate veteran Thomas Pinckney Tidwell, his wife Zera Ann (Passmore) Tidwell and other family members migrated from North Carolina to Texas. The Tidwells eventually settled in Alexander. Tidwell established this burial ground when a child of a Mexican family died and was not allowed burial in a local cemetery. Tidwell established a public burial ground open to area citizens regardless of religion or religious affiliation, and the Tidwell family donated an ornate cross to mark the child's burial site. However, the oldest dated grave is that of Sarah Ethetton (d. 1879), who was reinterred in the cemetery shortly after its establishment.

Among the notable burials in Alexander cemetery are those of community leaders and of veterans of military conflicts dating to the Civil War. The Alexander Cemetery Association cares for the burial ground. Today, the cemetery serves as a reminder of area pioneers and the former community of Alexander. As a place of free burial, Alexander Cemetery also continues as a monument to charity and human compassion represented by Thomas Pinckney Tidwell's offer to a family in need.
