Centennial is often associated with the community of Brownwood, as the communities are in close proximity. A stagecoach route between Augusta and “Sand Town,” now known as Newborn, ran through both communities. Centennial began to take its own identity with the creation of Centennial Church in 1880, and the construction of Centennial School a year later. Moseley’s Church and School were also located in the Centennial area. Centennial is also associated with the community of Austin, although there is some evidence that the communities were one and the same.

Austin:   The Austin community is geographically located beside the area traditionally identified as the Centennial community. Austin had a post office, established in the 1890's.However, it is possible that the post office, named "Austin," was actually the post office for Centennial.
