The community of Trio, was named for a trio of brothers, William D. Bryan, Walter R. Bryan, and James Bryan, who relocated to the area from North Carolina during the late 19th century to establish a turpentine business along the Georgetown and Western Railroad.[2][3] In 1883 the Bryan brothers established a post office and officially named the community Trio, pronounced "Try-oh" in the local dialect.[2][3] A small community subsequently grew around the post office.[2]
The two-story brick building that originally housed the Trio Post Office served multiple purposes for local residents throughout the twentieth century.[3] It functioned as a rural store, health clinic, and financial institution, known as The Bank of Trio.[3] The building is no longer in use today, and is in a state of disrepair, but remains a local landmark.[3]
The community of Trio has an AME church on Trio road, a fire station, the Bank of Trio/Trio Post Office, and 2 convenience stores as well as houses.
