I don't know if this will help or muddy the waters more.I have a Cynthia "Sintha" Wofford/Waford/Wafford who married Wesley Cooley 3 May 1833 Jackson Co. Ga.They had two known children Thomas b. 1836 and Doleska b.1839.
After Wesley Cooley's death Cynthia married Hiram Allen. Hiram's son from his first marriage,, Isom Allen married Doleska Cooley, his stepsister after his first wife, Martha Wofford/Waford/Wafford died.
As you can see they kept it in the family so seeing the name Allen and Cooley together made me wonder.
Part of the family stayed in and around Jackson Co. Ga.Part of the family moved to Talladega Co. Alabama.Most I haven't a clue where they went or who they married. Thomas had a total of 16 children by his two wives.I don't have a Susan listed for him.
But it wouldn't hurt to try to check this family out more,, especially with the Cooley-Allen connection
