It is associated with a tenant house and the Pennock family's iron works.","why_significant":"The nomination argues the mansion is the township's earliest and best surviving component of an industrial complex tied to the iron and paper industries. It is regarded as a departure from the township's predominant vernacular style, reflecting the wealth of the Pennock family. Its Federal detailing is described as compatible with houses built at the same time along the Philadelphia and Lancaster Turnpike.","narrative":"Built in the Federal style of stone with stucco facades, this two-story mansion stands on a site beside Buck Run in East Fallowfield Township, Chester County, Pennsylvania. It was completed about 1825 by Martha Pennock, widow of Isaac Pennock, whose Federal slitting mill on the stream had been rebuilt after his death and named Rokeby Iron Works. The house has an asphalt shingled gable roof, lipped chimneys at both gable ends, pedimented dormers, a box cornice, and a transom-lit central entrance. Nearby, a tenant house and a c1840 Greek Revival building complete the grouping. The property is significant for its link to the iron and paper industries that brought prosperity to the township in the nineteenth century. Later the Broomell family converted the complex to a paper mill, which operated until a fire in 1901. Its architectural integrity has been maintained by successive owners.","period_of_significance":"1820-1860","architect_builder":null,"architectural_style":"Federal","criteria":["A","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 17:11:32.103671-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/85001149.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/85001149/cb7fe26564-800.webp","url_1600":"https://nationalhistoricalregister.com/media/85001149/cb7fe26564-1600.webp","licence":"CC BY-SA 3.0","author":"JERRYE &amp; ROY KLOTZ MD","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:MARTHA_PENNOCK_HOUSE.jpg\" rel=\"noopener\">JERRYE &amp;amp; ROY KLOTZ MD</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:MARTHA_PENNOCK_HOUSE.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71992635","wikipedia":"https://en.wikipedia.org/wiki/Martha_Pennock_House","wikidata":"https://www.wikidata.org/wiki/Q6774514"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/chester-county/pennock-martha-house-85001149/"}
