The main house has a stone core, which was the original kitchen with a cooking fireplace and bake oven, joined to a brick main block. The farm was established in the 1750s, and most of its buildings date from the early to mid 19th century. The stone barn was in place by 1830 and was enlarged in 1877 by Robert B. Lamborn, who also rebuilt the shop and added a slaughterhouse. The property is significant for its long agricultural use and its links to the Underground Railroad. Isaac and Thamazine Meredith's home was a station on the route through the township. The farm was also associated with the Buffington family, who helped support Indian Hannah, the last Lenape in Chester County. It was designated a Century Farm in 1978.","period_of_significance":"1780-1820","architect_builder":null,"architectural_style":"PennPlan core","criteria":[],"status_note":"The farm is still in the Roberts family's ownership and maintained as a working farm.","vacant_flag":false,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:32.964106-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/85002372.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/85002372/5d87022bf3-800.webp","url_1600":"https://nationalhistoricalregister.com/media/85002372/5d87022bf3-1600.webp","licence":"Public domain","author":"Smallbones at en.wikipedia","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Indian_Deep_green_barn.jpg\" rel=\"noopener\">Smallbones at en.wikipedia</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Indian_Deep_green_barn.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71992615","wikipedia":"https://en.wikipedia.org/wiki/Indian_Deep_Farm","wikidata":"https://www.wikidata.org/wiki/Q6020224"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/chester-county/indian-deep-farm-85002372/"}
