It groups several farmstead clusters, a cemetery and natural features, and adds to the earlier-listed Dean Family Farm house and barn.","why_significant":"The district is presented as a rural historic landscape that shows how one family farmed and shaped the same land for over 180 years. It is eligible under Criterion A for Exploration/Settlement and Agriculture, and under Criterion C for Architecture, including a Federal-style brick farmhouse and a German bank barn typical of the Virginia Military District.","narrative":"Dean Family Farm Historic District covers roughly 540 acres southeast of Xenia in Greene County, Ohio, along Caesar's Creek. Daniel Dean brought his family here in 1812, and descendants have farmed the land since. The district is made up of several clusters: the original Dean-Hardie homestead with a small hall-and-parlor house and an English barn; Breakfast Rock, a glacial boulder tied to family folklore; the Huston-Noble cluster with a Queen Anne style house and barn; the walled family cemetery with about 80 markers; and the Robert A. Dean cluster. That last group centers on a two-story Federal brick farmhouse and a German bank barn, both listed earlier in 1975. Fields, pastures, old quarry workings and mature trees complete the landscape. The district was listed for its role in settlement and agriculture and for its architecture, showing how generations of one family adapted buildings and land use over time. Its period of significance runs from 1812 to 1944.","period_of_significance":"1812-1944","architect_builder":null,"architectural_style":"Early Republic; Mid-19th Century (Federal-style house, English and German bank barns, vernacular Queen Anne house)","criteria":["A","C"],"status_note":"Still in agricultural use, with a single dwelling, farm fields, animal facilities and a cemetery; a small log house is unoccupied and dilapidated.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:52:07.033819-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/94001300.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71988722","wikipedia":null,"wikidata":null},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/greene-county/dean-family-farm-historic-district-boundary-increase-94001300/"}
