It is known as General Howe's Headquarters.","why_significant":"The house served as General William Howe's headquarters from September 11 to 16, 1777, after the Battle of the Brandywine, and Dr. Benjamin Rush was received there to treat American wounded. The nomination also argues it is architecturally significant for its wealth of eighteenth and nineteenth century construction and its modifications across generations, and as the homestead of the Quaker Gilpin family, whose members included scientists, officials and inventors.","narrative":"Built in stages beginning in 1754 on a site occupied by Gilpin dwellings since the late 1690s, this stuccoed Pennsylvania farmhouse in Birmingham Township, Delaware County, shows construction methods from two centuries in one building. The original brick portion contains a 1754 datestone, and its basement walls may predate that year. A middle section is presumed to date to around 1811, and a half-width eastern wing was added later, with a double garage attached in 1949. General William Howe used the house as his headquarters after the Battle of the Brandywine in September 1777, and Dr. Benjamin Rush came there to treat American wounded. Bloodstains from British wounded are said to remain beneath later hardwood flooring. The Gilpin family, Quakers, produced a scientist, a governor, inventors and a U.S. Attorney General, and the property is also noted for apple varieties grown on the farm.","period_of_significance":"1777","architect_builder":null,"architectural_style":"Prototype of a Pennsylvania farmhouse","criteria":[],"status_note":null,"vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:30.110334-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/71000700.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/71000700/d7144d357b-800.webp","url_1600":"https://nationalhistoricalregister.com/media/71000700/d7144d357b-1600.webp","licence":"Public domain","author":"User:Smallbones on English Wikipedia.","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Gilpins.JPG\" rel=\"noopener\">User:Smallbones on English Wikipedia.</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Gilpins.JPG"},"district":{"nrhp_refnum":"66000660","name":"Brandywine Battlefield","url":"https://nationalhistoricalregister.com/districts/pennsylvania/brandywine-battlefield-66000660/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71994957","wikipedia":"https://en.wikipedia.org/wiki/Gilpin_Homestead","wikidata":"https://www.wikidata.org/wiki/Q5562576"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/delaware-county/gilpin-homestead-71000700/"}
