Leonard McGuff of Attala Co.MS, 1843

Hello. I have been trying for years to tie my Great Grandmother Sarah E. McGuffey (b.1842), her brother James M. (b.1841) and sister Francis (b.1845) to a preceding generation. They were born in Attala County and their parents (apparently deceased by 1847) were from GA. I have just yesterday discovered a Leonard McGuff on the 1843 tax roll of Attala County MS and found he was not there by the time of the 1848 (extant) tax roll.Does anyone know anything about this Leonard, who he married, and if he was the father of these three children, who were supposed to have been raised in the James Wallace household after their parents' death? Thanks.
