It also reflects the early settlement of Middle Granville under the Dayton family and the later Welsh immigrant investment in the slate industry, represented by Benjamin Williams, who lived there from the 1860s until his death in 1896.","narrative":"Built around 1820 at the corner of Dayton Hill Road and Route 22A in Middle Granville, this two-story brick house follows the traditional five-bay, end-gable Federal format. Its front wall is laid in Flemish bond and its windows have splayed marble lintels. Interior features include a fluted and reeded parlor mantel, a built-in dining room cupboard and a dog-leg stair. Several details were adapted from the pattern books of Asher Benjamin. Later changes include a frame kitchen wing added around 1880, loss of the lower parapet sections, and a modern bathroom. The house was probably built for a member of the Dayton family, whose patriarch, Captain Abraham Dayton, ran a local tannery. From 1864 until 1896 it was the home of Benjamin Williams, a Welsh-born businessman who became prominent in local business, community and political life and was linked to the slate industry. The property also includes a garage, fieldstone retaining walls and the foundation of a former worker house.","period_of_significance":"c. 1820-1896","architect_builder":null,"architectural_style":"Early Republic; Federal","criteria":["A","B","C"],"status_note":"Still in use as a single dwelling; the form lists its current function as domestic, single dwelling.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:51:53.722369-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/06001000.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/06001000/1ce9779a8c-800.webp","url_1600":"https://nationalhistoricalregister.com/media/06001000/1ce9779a8c-1600.webp","licence":"CC BY-SA 2.0","author":"Doug Kerr from Albany, New York, United States","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Dayton-Williams_House_Jun_11.jpg\" rel=\"noopener\">Doug Kerr from Albany, New York, United States</a>, <a href=\"https://creativecommons.org/licenses/by-sa/2.0\" rel=\"license noopener\">CC BY-SA 2.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Dayton-Williams_House_Jun_11.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75322825","wikipedia":"https://en.wikipedia.org/wiki/Dayton-Williams_House","wikidata":"https://www.wikidata.org/wiki/Q5243490"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/washington-county/dayton-williams-house-06001000/"}
