As planned, this Courthouse was begun in 1875; but before its completion, Franklin was named county seat, in 1879. Robert A. Brown, a merchant, investor and planter, purchased this building in 1885. With help of his wife, Lucy Herndon Brown, he made it into a residence. In 1909 his heirs sold it to Mrs. Fannie L. Hammond, in whose family it remained until 1966, when it became a museum.
