It is an approximately one and a third acre cemetery with three sections granted in 1690, 1721 and 1788.","why_significant":"The cemetery is argued to be one of the two oldest burying places in Bucks County and to contain the only seventeenth century gravestone in the county, dated 1698. It also holds one eighteenth century gravestone dated 1753 and the graves of six free African Americans who served in Volunteer Colored Regiments during the Civil War.","narrative":"Slate Hill Cemetery in Lower Makefield Township, Bucks County, holds burials dating from 1698 to 1918 across three sections granted in 1690, 1721 and 1788. The oldest section was granted by Thomas Janney to the Falls Meeting of Friends, and the Anderson section was granted to the township as its first public cemetery. Most burials in the Friends section predate 1800, and their markers are plain brownstones with no carving, engraved only with names and dates. The cemetery contains the only seventeenth century gravestone in Bucks County, dated 1698, and an eighteenth century stone dated 1753. Its public section includes six free African Americans who served in Volunteer Colored Regiments during the Civil War. These men came from a free Black community in Yardleyville that had its roots in Quaker manumission. The cemetery is valued for its early gravestones, its Quaker burial traditions and its connection to that community, and it retains very good integrity.","period_of_significance":"1698-1908","architect_builder":null,"architectural_style":null,"criteria":["A","D"],"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 17:11:37.459656-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/92000397.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/92000397/d7dd74beec-800.webp","url_1600":"https://nationalhistoricalregister.com/media/92000397/d7dd74beec-1600.webp","licence":"CC BY-SA 3.0","author":"Shuvaev","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Slate_Hill_Cemetery,_Morrisville_PA_02.JPG\" rel=\"noopener\">Shuvaev</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:Slate_Hill_Cemetery,_Morrisville_PA_02.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71996630","wikipedia":"https://en.wikipedia.org/wiki/Slate_Hill_Cemetery","wikidata":"https://www.wikidata.org/wiki/Q7538833"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/bucks-county/slate-hill-cemetery-92000397/"}
