I have a John Addison b. 1785 SC and wife Libby b. 1786 SC in the 1850 Bradley Co., TN Census. I believe they came to TN via Gwinnett Co., GA. I am hunting for information on John and his wife.His daughter Elizabeth b. 1820 GA married Daniel White b. 1810 SC. Could this John be the John Addison who you mention as the son of John Addison and Tamson Ralph? Please contact me with more details on this line. Your help will be greatly appreciated.
