- Three post offices on this list cannot be verified via postal public records: Blaylock House, Chinquapin Grove, and Little East Fork. Information about the Blaylock House is derived from oral history contained in My Children’s Children: The Murray Clan by Frances Blalock Denton. Chinquapin Grove data comes from Norman Long whose family lived in the building known as Chinquapin Grove School. According to family oral history, at varying times, the structure served as a school, a church, a post office, and a home. There is no verifiable data about Little East Fork as a post office; rather, it appears to have been a delivery route.
- Livingston Post Office may not have been in Bethel. The precise location has not been verified. The post office, however, was on the delivery route from Waynesville that serviced other Bethel postal deliveries: Lavinia, Retreat, and Sonoma Post Offices.
