I have recently found Amelia Co., Va. documents that disclose the birth years for several members of Bryan Fannin(g), Sr.'s immediate family members. Until now, these dates have only been an estimate, but the documentation substantiates the birth years suggested.
Achilles Fannin, Sr. b. 1728 - 1730 Bryan Fannin, Jr. b. 1728/1730 Laughlin Fannin b. 1746/1747 Jehu (John) Fannin b. 1746/1747 William Fannin (son of Achilles) b. 1749/1750
I have two files of documentation on this. If anyone would like copies, please contact me at firstname.lastname@example.org.
