It is also known as the Growden-Galloway House and the Gen. James Wilkinson House.","why_significant":"The nomination argues the manor is significant for its associations with prominent historical figures, particularly Joseph Growden, Joseph Galloway, and General James Wilkinson, and their roles in the Revolutionary and Loyalist movements. It also cites the manor's architecture as one of the more imposing in Bucks County despite later alterations, with a center hall plan and courtyard that are English in conception.","narrative":"Trevose Manor is a two-and-a-half-story stone manor house in Cornwells Heights, Bucks County, Pennsylvania, built around 1685 with a hip roof, five bays across the front, and a center hall plan. It was built for Joseph Growden, a judge and close associate of William Penn who helped formulate the Charter of Privileges. A third story was added in 1847, when the original pointed stone was covered with stucco and interior woodwork was removed. The house later belonged to Growden's granddaughter's husband, Joseph Galloway, a prominent colonial Speaker of the Assembly who became a Loyalist; Benjamin Franklin visited often. Patriot forces ransacked and partly burned the estate. In 1782-83 General James Wilkinson occupied the house. The manor is regarded as significant for these associations with Revolutionary-era political conflict and for its architecture, which was among the more imposing in the county.","period_of_significance":"c. 1685-1847","architect_builder":null,"architectural_style":"Georgian; Greek Revival period elements","criteria":[],"status_note":"The manor house is currently occupied; the stone wings are in ruins.","vacant_flag":false,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:29.215505-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/76001607.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/76001607/af2258f429-800.webp","url_1600":"https://nationalhistoricalregister.com/media/76001607/af2258f429-1600.webp","licence":"CC BY-SA 4.0","author":"User:Magicpiano","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:BensalemPA_GrowdenMansion.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:BensalemPA_GrowdenMansion.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71995160","wikipedia":"https://en.wikipedia.org/wiki/Growden_Mansion","wikidata":"https://www.wikidata.org/wiki/Q5611616"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/bucks-county/trevose-manor-76001607/"}
