Its monitor roof is unusual on a residence, and it later housed workers from the Hamilton Woolen Mill. The form says it may have influenced the monitor-roofed Girls' Boarding House.","narrative":"Standing at 915 West Main Street in Southbridge, this two-story, five-bay brick house dates to about 1815 and combines a fanlighted entrance with a monitor roof, a feature more often seen on mill buildings. Its origins are unclear, but it appears in an 1822 painting of Globe Village by Francis Alexander and seems to have been built as a residence. By the mid-19th century it was apparently housing workers from the Hamilton Woolen Mill across the street, and maps from 1855 show the mill company as owner. William McKinstry, Jr., a tailor and son of an early Southbridge settler, was recorded as living here in 1836. The monitor roof may have inspired the similar roof on the mill's later Girls' Boarding House, since it added living space cheaply. Porches were added in the 1890s and early 20th century. The house is valued as rare surviving housing from the early mill development of Globe Village and for its architecture.","period_of_significance":null,"architect_builder":null,"architectural_style":"Federal","criteria":["A","C"],"status_note":"Present use is residential; condition is described as good-fair.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:13:00.730285-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/61/7934/63793461/content/electronic-records/rg-079/NPS_MA/89000528.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/89000528/50d0775437-800.webp","url_1600":"https://nationalhistoricalregister.com/media/89000528/50d0775437-1600.webp","licence":"CC BY-SA 4.0","author":"User:Magicpiano","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:SouthbridgeMA_WilliamMcKinstryJrHouse.jpg\" rel=\"noopener\">User:Magicpiano</a>, <a href=\"https://creativecommons.org/licenses/by-sa/4.0\" rel=\"license noopener\">CC BY-SA 4.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:SouthbridgeMA_WilliamMcKinstryJrHouse.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/63793461","wikipedia":"https://en.wikipedia.org/wiki/William_McKinstry_Jr._House","wikidata":"https://www.wikidata.org/wiki/Q8015471"},"indexable":true,"url":"https://nationalhistoricalregister.com/massachusetts/worcester-county/mckinstry-william-jr-house-89000528/"}
