I am reasearching Thomas Clifford White (b. about 1857; Hall County, GA). He married Georgia A. Calaway 17 Feb 1881 in Gwinnett & had 3 children Cora in 1882(my g-g-grandmother); Nancy Victoria in 1885 and Burl Shelton (unknown DOB). My prelimenary research leads me to believe he was the son of Butler White (b.1807-1817; NC) & Nancy Compton (b. abt 1814 in SC).
According to my research, Thomas Clifford White's brothers and sisters would have been Garrison L. White, Tina White, Lucinda White, and more brothers named only as initials, JH, JR & GB. (all born 1837-1854 in/around Hall Co., GA.) Does any of this fit in with your Whites that you're researching?
