The house is oriented east toward Pennsylvania Route 416 on a slope above the Welsh Run creek.","why_significant":"The nomination argues the house is significant for its architecture as a representative of regional vernacular building traditions, with a log section and successive additions that show several periods of construction. It also cites social and humanitarian significance through its role in the village, including its use as the local post office for part of its history.","narrative":"Along a slope above Welsh Run in Montgomery Township, Franklin County, Pennsylvania, stands a farmhouse built in stages through the 19th century. Its oldest part is a log section with three bays on the north, apparently dating from the first quarter of the 1800s, to which a mid-19th-century addition of timber frame with brick nogging or log was joined on the south. The house has board and batten siding, a slate roof, and a main entrance with a nine-panel door and diamond-pane transom. A stone springhouse and a frame stable stand nearby. The house served for part of its history as the village post office, kept by Thomas Bowles, who owned it from 1840. Its interior woodwork, fireplaces and later Victorian alterations make it a readable record of successive building periods in the local vernacular tradition, and it is valued for that reason.","period_of_significance":"1800-1899","architect_builder":null,"architectural_style":null,"criteria":["C"],"status_note":"The document describes the buildings as appearing to be in excellent condition and notes the front porch and upper-story door are 20th-century or no longer in use; it does not state current use beyond that.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:28.873759-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/79002231.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/79002231/146e5d5567-800.webp","url_1600":"https://nationalhistoricalregister.com/media/79002231/146e5d5567-1600.webp","licence":"CC BY-SA 4.0","author":"JERRYE &amp; ROY KLOTZ M.D.","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:ANGLE_FARM,_FRANKLIN_COUNTY,_PA.jpg\" rel=\"noopener\">JERRYE &amp;amp; ROY KLOTZ M.D.</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:ANGLE_FARM,_FRANKLIN_COUNTY,_PA.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71996506","wikipedia":"https://en.wikipedia.org/wiki/Angle_Farm","wikidata":"https://www.wikidata.org/wiki/Q4763340"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/franklin-county/angle-farm-79002231/"}
