I wish that I did know Jesse Poplin's parentage. I have corresponded with Poplin researchers that trace their lineage through Richard and Henry (Mongomery County, 1790 census and believed to be formerly of Chatham) and they seem pretty certain that Jesse is not one of theirs. David Kirk Shaver, contributing author of a book on Stanly County NC cemetery records says the following underneath an entry for my ggrandfather David C. Poplin (grandson of Jesse Sr.) "It has been discovered by this line, just above - of Poplins, that their identity has been lost. When the Poplins of Stanly County started searching for their ancestory it was discovered that this one line's pioneer grandfather had changed his name from a Slavic name, very similar to Poplin - to Poplin. All that is known is that it was something like or similar to Poppavitch or some such name."
It is a bit hard to picture a wandering Slav in Colonial Piedmont NC (not impossible though. The possibility of Peebles or one of the variants that are recorded (Pupliz or Popoliz) in NC being contorted into Poplin seems more plausable.
Thank you for Lucy's last name. I did not know it.
