Hannum led local military units during the Revolution and held civic and legislative posts, including a role in moving the county seat that led to West Chester. The nomination also cites his capture by British forces and later escape.","narrative":"Built circa 1760 of fieldstone, this two and one-half story gable-roofed house in Marshallton, Chester County, has a Georgian plan with massive lipped gable-end chimneys, a recessed front entrance with an elliptical fanlight, and twelve-over-twelve sash on the first floor. Additions include a two-story wing, a hip-roofed section built into the hillside, and a fieldstone garage. Col. John Hannum built the house and lived there throughout a long career in public service. Political and military plans for the region were discussed within its walls. Hannum served as a Provincial Justice of the Peace, sat in the General Assembly from 1781 to 1785, and was a delegate to the Pennsylvania convention that ratified the Federal Constitution in 1787. He spearheaded moving the county seat from Chester to a more central site that became West Chester. During the Revolution he commanded Chester County battalions as Lieutenant Colonel or Colonel. He was captured by British forces, imprisoned in Philadelphia, and then escaped to rejoin his men.","period_of_significance":null,"architect_builder":null,"architectural_style":"Georgian","criteria":["A","C"],"status_note":"Condition is marked good and the property is marked altered.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:34.518623-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/80003463.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/80003463/b249b408fd-800.webp","url_1600":"https://nationalhistoricalregister.com/media/80003463/b249b408fd-1600.webp","licence":"CC BY-SA 3.0","author":"JERRYE &amp; ROY KLOTZ M.D.","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:COLONEL_JOHN_HANNUM_HOUSE.jpg\" rel=\"noopener\">JERRYE &amp;amp; ROY KLOTZ M.D.</a>, <a href=\"https://creativecommons.org/licenses/by-sa/3.0\" rel=\"license noopener\">CC BY-SA 3.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:COLONEL_JOHN_HANNUM_HOUSE.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71996411","wikipedia":"https://en.wikipedia.org/wiki/Col._John_Hannum_House","wikidata":"https://www.wikidata.org/wiki/Q5141772"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/chester-county/hannum-col-john-house-80003463/"}
