Hi Gayle :) Have you talked to a Harvey Kornegay? He has done a lot of research in the Kornegay lineage and knows a guy who traces the kornegay name all the way back to Germany. I don't remember though if Harvey ever found the connection between William Jesse and the rest of the Kornegay family. Let me know if you want to contact him and I'll give you his email address.
Haha. for all I konw, we saw each other at the last Kornegay family reunion and I just don't remember you lol... I'm terrible with remembering people. lol sorry :)
