Its lavish architectural detail adds to that significance. It also represents the second generation of the Dayton family in Madison.","narrative":"Built around 1866, this two-and-a-half-story frame house at 417 West Main Street in Madison, Ohio, is a well-preserved example of Second Empire design. A mansard roof with a metal deck carries seven pedimented dormers, and a bracketed eaves cornice with dentils runs beneath it. Round-arched windows have heavy hood moldings, while rectangular windows have drip molds. An entrance balcony rests on brackets, and a railed platform marks the side entrance. The house sits on a sandstone foundation, is clad in flush siding, and has an ell-shaped plan. A frame carriage house is built into the sloping rear of the lot, which also has many trees and a creek. Local tradition holds that the house was paid for with mustering-out pay after the Civil War. It was listed because it is the only complete mansard Second Empire building in the village, and its elaborate detailing strengthens that distinction. It also reflects the second generation of the Dayton family in Madison.","period_of_significance":"ca. 1866","architect_builder":null,"architectural_style":"Second Empire","criteria":[],"status_note":"Used as a residence; interior and exterior condition both listed as excellent.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:53:12.333398-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/80003115.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/80003115/5c795964a6-800.webp","url_1600":"https://nationalhistoricalregister.com/media/80003115/5c795964a6-1600.webp","licence":"CC BY-SA 3.0","author":"LeeG7144","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:417_W_Main_St.jpg\" rel=\"noopener\">LeeG7144</a>, <a href=\"https://creativecommons.org/licenses/by-sa/3.0\" rel=\"license noopener\">CC BY-SA 3.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:417_W_Main_St.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71985618","wikipedia":null,"wikidata":"https://www.wikidata.org/wiki/Q138436150"},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/lake-county/dayton-james-house-ii-80003115/"}
