I have been looking thru census records in Warren County for 1810 and 1820. (Looking mostly for Peter and Micajah Walker.) In 1810 there are 15 Walker's listed. In 1820 there are only 5. Does anyone who knows the history of the area have an idea why so many would have left at that time? As far as I can tell there was no county line change at that time to account for the change. Paula
