Built in 1812, it is set on a banked lot facing south over agricultural fields.","why_significant":"The nomination argues the house is a significant example of the full Georgian-plan masonry farmhouse found among Cumberland County's wealthier agriculturalists in the nineteenth century. Its interior woodwork, including elaborate corner cupboards and fireplace mantels, is described as remarkably intact and among the finest federal-era woodwork in the county.","narrative":"Built in 1812 by George Trimble on a farm in Silver Spring Township, Cumberland County, this five-bay, double-pile brick house has a stone foundation, a rear kitchen ell and a true Georgian plan with a central passage flanked by four equal rooms, each with a fireplace. Its main block retains plaster walls, pine floors and nearly all of its federal-era interior woodwork. The southeast parlor contains an elaborate corner cupboard rising the full height of the room, with a matching fireplace mantel, and the house has a second corner cupboard in the western parlor. Exterior alterations in the 1940s and 1960s, including a new porch and sunporch, did not affect the interior. The house is important as an example of the masonry farmhouses built by prosperous Cumberland County families in the early nineteenth century, and its woodwork is regarded as among the finest of its period in the county.","period_of_significance":"1812","architect_builder":null,"architectural_style":"Early Republican/Federal; Georgian plan","criteria":["C"],"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 17:11:36.184703-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/92000945.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/92000945/e97be0dc77-800.webp","url_1600":"https://nationalhistoricalregister.com/media/92000945/e97be0dc77-1600.webp","licence":"CC BY-SA 4.0","author":"Jerrye &amp; Roy Klotz, MD","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:GEORGE_TRIMBLE_HOUSE,_CUMBERLAND_COUNTY.jpg\" rel=\"noopener\">Jerrye &amp;amp; Roy Klotz, MD</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:GEORGE_TRIMBLE_HOUSE,_CUMBERLAND_COUNTY.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71996464","wikipedia":"https://en.wikipedia.org/wiki/George_Trimble_House_(Mechanicsburg,_Pennsylvania)","wikidata":"https://www.wikidata.org/wiki/Q5545322"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/cumberland-county/trimble-george-house-92000945/"}
