Marsha, This David could be the son of Robert Busby on the 1820 Humphreys co. census sais that he only has 1 son under 10. David is on the 1840 Benton co. Tenn. census which is next to Stewart and Humphreys co. I have not been able to find out any of Roberts daughters they are harder to find out unless you have marriage records. The information that I posted was pretty much all I have on Robert Busby. Jeff Busby Boise, Idaho
