It was included in a township historic resources survey and is classified under education and nineteenth-century architecture. The form gives little further argument for its significance.","narrative":"Located at 6273 Cosgray Road in Amlin, Washington Township, Franklin County, Ohio, this one-story cut stone building dates to roughly 1860-70. It was built as a schoolhouse and now serves as a private residence. The building has a gable roof, a three-bay front and three-bay sides, and arched windows. Decorative brickwork is noted in the gable, including sawtooth patterning, and the survey also records a later addition. Its exterior condition is described as good. The setting is flat farmland, with a garage and shed nearby and a setback from the road. The property was recorded during a survey of Washington Township historic resources, where it is identified as one of only two township schoolhouses that have been converted to residences. That survival of a mid-nineteenth-century rural school, adapted to a new use, is the main basis given for its inclusion. The surviving record is brief and does not name a builder or architect.","period_of_significance":"1860-70","architect_builder":null,"architectural_style":null,"criteria":[],"status_note":"Originally a schoolhouse, now a residence; exterior condition recorded as good.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:53:11.960716-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/79002887.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/79002887/060c0b1e73-800.webp","url_1600":"https://nationalhistoricalregister.com/media/79002887/060c0b1e73-1600.webp","licence":"Public domain","author":"Nyttend","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:J.L._Hamilton_Residence.jpg\" rel=\"noopener\">Nyttend</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:J.L._Hamilton_Residence.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71985254","wikipedia":null,"wikidata":"https://www.wikidata.org/wiki/Q137803709"},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/franklin-county/hamilton-j-l-residence-79002887/"}
