It is the only Second Empire example in the southern half of the township. Its largely unaltered agricultural setting is also notable, since much nearby farmland has become suburban development.","narrative":"Built around 1883, this three-story brick farmhouse on Union Road in southern Franklin Township, Warren County, Ohio, applies the Second Empire style to a working farm. Its L-plan form has a patterned slate mansard roof, dormer windows, a slightly projecting central pavilion, a truncated front gable with a scroll finial, and bracketed trim. A small two-story rear wing uses bricks from an earlier Deardoff farmhouse. Daniel L. Deardoff bought the farm from his father in 1869; the family had held the land since 1805. The house's size and style set it apart from more modest neighboring farmhouses, suggesting Deardoff's success as a farmer in a township that prospered from the canal, turnpike and railroads. It is the only Second Empire building in the southern half of the township. Connected barns and other outbuildings survive nearby, and fields still surround the house, giving it unusual integrity in an area that has seen suburban development.","period_of_significance":"1800-1899","architect_builder":null,"architectural_style":"Second Empire","criteria":["A","C"],"status_note":"Occupied as a private residence; described as in good condition, with a small one-story addition from about 1975 and bathroom and kitchen alterations.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:53:14.270755-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/84003810.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71991828","wikipedia":null,"wikidata":null},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/warren-county/deardoff-daniel-l-house-84003810/"}
