The house is regarded as a late 18th century German-plan farmhouse.","why_significant":"The nomination argues the house is one of only a few remaining unaltered 18th century farmhouses in Montgomery township and an example of 18th century farm life that has largely disappeared from the area. It states the house retains original interior woodwork, floors and doors, with changes limited to indoor plumbing and electricity. Its association with the Moore and Knapp families and an alleged 1777 stay by George Washington are also cited.","narrative":"A two-and-a-half story stone farmhouse with a stuccoed exterior and a German floor plan stands on a farm in Montgomeryville, Montgomery County, Pennsylvania. The eastern section, with its large kitchen fireplace and winding stair, is believed to predate the western section by a few years, with construction placed around 1760 and 1770. The house was probably built by John Roberts, Jr., who held the land from 1756 to 1768. Dr. Samuel Preston Moore and his brothers lived there for more than half a century, and an alleged stay by George Washington in October 1777 is recorded. John Hawley Worrell bought the farm in 1835 for his daughter Mary and her husband Abiriam P. Knapp, and the Knapp family has worked the land since. Original pine floors, hand-hewn joists and plank doors survive throughout. The house is regarded as a rare example of 18th century farm life in a township that has since been heavily developed.","period_of_significance":"1760-1825","architect_builder":null,"architectural_style":null,"criteria":[],"status_note":"Maintained to a late 18th century character; the barn and utility sheds date from 1894.","vacant_flag":false,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:30.220879-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/76001656.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/76001656/7650b13da2-800.webp","url_1600":"https://nationalhistoricalregister.com/media/76001656/7650b13da2-1600.webp","licence":"CC BY-SA 3.0","author":"Shuvaev","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Knapp_Farm_01.JPG\" rel=\"noopener\">Shuvaev</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:Knapp_Farm_01.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71996602","wikipedia":"https://en.wikipedia.org/wiki/Knapp_Farm","wikidata":"https://www.wikidata.org/wiki/Q6421750"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/montgomery-county/knapp-farm-76001656/"}
