The Piscataway were pushed north on the Potomac River early in their history, coming to be cut off from the rest of their people. While some stayed, others chose to migrate west. Their movements are generally unrecorded in the historical record, but they reappear at Fort Detroit in modern-day Michigan by the end of the 18th century. These Piscataways are said to have moved to Canada and probably merged with the Mississaugas, who had broken away from the Anishinaabeg and migrated southeast into that same region. Despite that, many Piscataway stayed in Virginia and Maryland until the modern day. Other members of the Piscataway also merged with the Nanticoke.
