Its house is described as an exceptional hybrid of Georgian and Victorian design with high integrity. The farm also retains evidence of early mill and tanning industries and a rare two-level outbuilding with overhang.","narrative":"Along Potter's Run near Potters Mills, the Potter-Allison Farm holds a brick house built in two stages: a Georgian section from about 1817 and an 1850s Victorian addition built under William Allison, who had acquired the property from James Irvin. The house keeps its symmetrical facade, side hall plan, 12-over-12 facade windows and a panelled entrance door, along with Victorian cabinetwork and a mantled parlor fireplace. The farm stands on land tied to General James Potter, an early settler who arrived around 1768 and built a log house in 1788. The property was a continuous working farm into the early 20th century and includes a large bank barn with hand-hewn timbers, several outbuildings, and archeological traces of grist, saw, woolen and tanning mills. Its surviving buildings and integrity are considered rare for the county.","period_of_significance":"1800-1899","architect_builder":null,"architectural_style":"Georgian with Victorian addition","criteria":["A","C"],"status_note":"The house is described as standing in excellent condition; the nomination notes the farm was in continuous use as a farming operation until the early 20th century.","vacant_flag":false,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:29.657559-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/77001143.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71994941","wikipedia":"https://en.wikipedia.org/wiki/Potter%E2%80%93Allison_Farm","wikidata":"https://www.wikidata.org/wiki/Q7235239"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/centre-county/potter-allison-farm-77001143/"}
