Your family is most likely the French families, commonly spelled PAULIN, POULIN, etc.When you are searching, if you find a family with first names that sound French (like Antoine, Pierre, Jean) that may be your line. My family is from England and the American line is descended from Henry PAULLIN, PAULIN, POWLING, etc. He is known within our line as "Henry the Immigrant" and lived in Bucks Co PA, with some descendants caught up in the land grant movement and moving ever westward as land was settled.Others remained in the PA/NJ area and are still there today. Henry PAULLIN was a Quaker. Spelling was not standardized until the late 1800's and various individuals spelled their surname differently, even if they were related. There are a variety of websites you can check, and some have family trees that others do not have.Good Luck!
