The original Federal-style block was built by Ira Davenport and was enlarged in the 1840s and again before 1888.","why_significant":"The house is a largely intact example of a substantial Federal period house in New York's Southern Tier. It was the home of its builder, merchant Ira Davenport, and later his nephew Martin Adsit, a leading figure in Hornell's nineteenth-century commercial and banking development. Adsit helped lobby to route the Erie Railroad through the Canisteo Valley.","narrative":"Built in 1828 by merchant Ira Davenport, this brick house at 34 Main Street in Hornell was the first brick building in the town and is now the oldest house within the present city limits. The original three-bay Federal block kept nearly all of its early interior layout. Davenport's nephew, Martin Adsit, bought the property in 1839 and added a two-story Greek Revival wing in the 1840s, with fluted porch columns and pilasters. A third brick wing, containing two duplex apartments, was added before 1888. Adsit lived here until his death in 1903. He became one of the most influential men in the region, running a dry goods store, founding and leading the First National Bank of Hornellsville, and lobbying to bring the Erie Railroad through the Canisteo Valley. The house is significant both as an intact Federal-period dwelling in the Southern Tier and as the home of these two figures, and it still contains apartments today.","period_of_significance":"1828-1903","architect_builder":"Ira Davenport, Builder","architectural_style":"Early Republic: Federal; Mid-19th century: Greek Revival; Late Victorian Eclectic","criteria":["B","C"],"status_note":"Currently used as multiple dwellings; the 1828 house and 1840s wing were divided into duplex units, and the north wing holds two duplex apartments.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:51:52.653706-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/03000047.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75321959","wikipedia":"https://en.wikipedia.org/wiki/Adsit_House","wikidata":"https://www.wikidata.org/wiki/Q4685832"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/steuben-county/adsit-house-03000047/"}
