Its farmhouse, barns and outbuildings show building types, materials and landscape patterns typical of the region.","narrative":"This 68-acre farmstead on Stone Road near Xenia, Ohio, grew from a log cabin settled around 1801 by Isaiah McDonald and his family. It now holds nine buildings and two sites, including a brick I-house built in 1839 in a blend of Federal and Greek Revival styles, a Pennsylvania German forebay barn from about 1829, a 1916 dairy barn, a spring house, a syrup barn, a family cemetery and a limestone quarry. Local limestone appears in the house foundation, lintels, porch, walkways and fence posts. The quarry supplied stone for local buildings, and in 1850 it provided the block Ohio contributed to the Washington Monument. The farm reflects the land patterns and building types of the Virginia Military District, and it moved into dairy farming and maple syrup production in the early twentieth century. The same family has kept it for generations, and its intact buildings and landscape record nearly two centuries of farm life.","period_of_significance":"1829-1946","architect_builder":null,"architectural_style":"Federal/Greek Revival; Other: I-House","criteria":["A","C"],"status_note":"Described as an intact working farm, mostly in good condition, with some deterioration: the older barn's replacement foundation is near collapse and the syrup barn's back side has collapsed.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:52:07.105905-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/96000673.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/96000673/25fbf0b4b3-800.webp","url_1600":"https://nationalhistoricalregister.com/media/96000673/25fbf0b4b3-1600.webp","licence":"Public domain","author":"Nyttend","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Main_barn_and_silo_at_the_McDonald_Farm.jpg\" rel=\"noopener\">Nyttend</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Main_barn_and_silo_at_the_McDonald_Farm.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71988760","wikipedia":"https://en.wikipedia.org/wiki/McDonald_Farm_(Xenia,_Ohio)","wikidata":"https://www.wikidata.org/wiki/Q6800902"},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/greene-county/mcdonald-farm-96000673/"}
