It was built in the early 1800s, probably between 1811 and 1815, by an unknown builder.","why_significant":"The nomination argues the house is tied to early settlers of Ohio and the Old Northwest Territory. It is also linked to the early growth of industry and commerce through Governor Thomas Worthington's mill enterprises. It is a rare surviving example of the architecture of Chillicothe's earliest important buildings, and resembles the first Ohio capitol and Adena.","narrative":"Built of broken-course cut sandstone, this two-story house on South Paint Street in Chillicothe sits beside Paint Creek and is known locally as the Old Stone House. It measures 20 by 49 feet, with a central entrance hall, equal-sized rooms on each side, radiating stone lintels with keystones, and pre-Victorian mantels and cabinetry inside. Its exact construction date is uncertain, but deed prices point to the period between 1811 and 1815. Governor Thomas Worthington bought it in 1815, and his daughter Mary and her husband David Macomb lived there while managing his nearby cloth mill, which was part of a trading network reaching from the East Coast to the Southwest. Later owners were pork packers, a major local industry. The house resembles Ohio's first capitol and Worthington's home, Adena, and its architectural character remains largely intact. Today it stands in a lumber yard, with only a metal lean-to shed added.","period_of_significance":"1800-1899","architect_builder":null,"architectural_style":null,"criteria":[],"status_note":"Listed as unoccupied and in fair condition, altered only by a one-story metal lean-to shed; it now stands on a 5.31-acre parcel in a lumber yard.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:53:09.911243-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/76001525.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/76001525/fdfd90f8bc-800.webp","url_1600":"https://nationalhistoricalregister.com/media/76001525/fdfd90f8bc-1600.webp","licence":"CC BY 2.0","author":"dok1","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Mary_Worthington_Macomb_House.jpg\" rel=\"noopener\">dok1</a>, <a href=\"https://creativecommons.org/licenses/by/2.0\" rel=\"license noopener\">CC BY 2.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Mary_Worthington_Macomb_House.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71991195","wikipedia":"https://en.wikipedia.org/wiki/Mary_Worthington_Macomb_House","wikidata":"https://www.wikidata.org/wiki/Q6780989"},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/ross-county/macomb-mary-worthington-house-76001525/"}
