Baker County was formed on December 30, 1868. It was named for Alfred Baker, with its county seat at Grantville. Residents of the county asked the Alabama legislature for the renaming of their county. In 1874, they chose the name Chilton County. William Parish Chilton, Sr. (1810–1871), was a lawyer who became Chief Justice of the Alabama Supreme Court. Later he represented Montgomery County in the Congress of the Confederate States of America. It is not known when the county seat was moved.
