Hi, I just entered two early Palmer people on the free Find A Grave web site at
Wilmington and Brandywine Cemetery Wilmington New Castle County Delaware, USA
Check to see if any of your people are buried there. There could be a connection.
I have also just asked for a look-up or list of people buried there.I suggest you try the same thing. Let me know if you find out anything about the burials there. I am looking for Hemphills and Palmers too. I noticed you mentioned one Palmer person.
