It is tied to pioneer farmer Daniel Dean, who bought the land in 1815. The house shows Federal style with Adams style detail, and the barn appears in an 1874 county atlas.","narrative":"Dean Family Farm is a brick farmhouse and barn along Ballard Road, about five miles west/northwest of Jamestown in Greene County, Ohio. The original house is a central hall Federal style building with a Flemish bond facade, a doorway with Adams style paneling, and a rough cut stone foundation. A later rear wing and a turn of the century two tier porch were added. Inside, the dogleg stair, board and batten doors and log cellar joists survive. A nineteenth-century barn with a hand hewn timber frame sits on a stone foundation. The farm reflects the settlement of Daniel Dean, an Irish-born pioneer who moved his family to Ohio around 1812 and bought the land in 1815. His holdings grew to over 1800 acres before his death in 1843, and the family still lived on the farm at the time of listing. The house was probably built about a decade before the family's claimed 1833 date. Highway construction nearby later led to a reduction of the nominated area.","period_of_significance":"1815-1833","architect_builder":null,"architectural_style":"Federal","criteria":[],"status_note":"Occupied private farm in good condition; the old part of the house has some rooms unused for a long time.
