Historical Society of Pennsylvania - Colonial-era records referencing Lenape

The Historical Society of Pennsylvania's manuscript and map collections include 17th- and 18th-century colonial records, land deeds, and maps that document transactions, place names, and interactions between Pennsylvania colonists and the Lenape (Delaware) people. Researchers use these primary-source materials to study treaties, land sales, and demographic changes in the Philadelphia region. The collections are frequently consulted for genealogical and legal-historical research related to Native-settler relations in southeastern Pennsylvania.
