The town of Bluford was named after Bluford "Bluf" Green (1868–1912) when he was a small boy  by his father Wiley Green (1835–1878), who was the local justice of the peace.
An extended story about Bluford by Mrs. Opal H. Wood, follows:
In 1881, before there was a Bluford, construction was started on the Air Line Railroad, later the Southern R.R. George Evans, Mt. Vernon banker, laid out the town on 40 acres of land bisected by the railroad. In 1882, Rev. Z. H. Byard, a United Brethren preacher built the first store building and dwelling. Byard also was the first postmaster in Bluford, and the first railroad station agent. Bluford was incorporated in 1925. Dwight Bressler was its first mayor.
Bluford spread on both sides of the railroad. The south section unofficially was called Tilford, and the north, Bluford, both being names of the sons of Minerva (Flint) and Wiley Green. When son Tilford died, all the town became Bluford. No reason was given why the boys should have been so honored.
