I wish I knew, Billy, whether or not Thomas had a brother named Jesse. There are several of us trying to sort out the SC Deen's. Have you considered taking the DNA test? Please do. We have found at least 4 of the Deen/Dean's who are related at sometime.....all from SC. You might be our missing link. The others spell the last name as Dean....but our Thomas E. kept the spelling as Deen. Some of his son's changed to Dean. There are many William's, Thomas's, etc in our line. Please join us in the DNA trails....it really does help.
