Harrison and Martha Ann McKinney Slaughter acquired 120 acres in this area from Jessie Sumner on May 20, 1862, and the settlement that developed here was first called Slaughter after this pioneer family before becoming known as Clay Sink for a local clay sinkhole. The cemetery on this hill of moss-draped oaks was established in 1873 when the Slaughters buried their infant daughter here, and many early settlers and their descendants are buried here. It is maintained in perpetuity by the Clay Sink Cemetery Association, Inc. The Clay Sink Missionary Baptist Church was organized on February 19, 1897, with twenty-one members and Elder G.A. Bryant as moderator. In 1904, a wood-frame building was erected on this site and served the congregation until the present pine building was constructed in 1956. The one-room Slaughter/Clay Sink school building was built in 1912 on Cobb Slough and moved in 1915 to this site, which was donated by William Henry and Joanna Slaughter Boyett. When the school closed in 1943 because of consolidation, the building became the church fellowship hall, and the teacher's raised platform remains part of the structure. Early settler families who were charter members of the church included the Slaughters, Sumners, Boyetts, Sapps, Robbins, McKinneys, Hardins, Mobleys, Gays, and Weeks, and descendants of these families still live in the area.
