Have you found any info on the Natives you were asking about? Local farmers tell me there were several families of Natives that lived around the Hershaull Park area of East Hopewell Twp. While I have yet to find anyone who remembers exactly what tribe they were from, it's possible that they were Shawnee, Seneca, Susquehannock, Conoy or Nanticoke. In all of my research I've found predominantly Shawnee in our area in 18th century forward, though.
I'm familiar with Strayer descendants living here now and one of them married into the Evans family who come from Saponi Natives. The Rineholts and Lefflers in my family come from those Native families I mentioned above in East Hopewell, late 1800s early 1900s. They were farmers. If you want to know more about various Pennsylvania Natives feel free to message me.
