I hope you are still researching this as I'd like to know what you have on Harris Allen.
I recently learned about Harris Allen and Sarah Hays, my gggg-grandparents. Their daughter Frances Allen married William Ashmore who was born about 1790. This should fit your time frame. I have 8 children for Frances and William born between 1829 and 1839 in Georgia. One son was named Harris Allen Ashmore. Their daughter, Mary Ashmore, is my gg-grandmother who married Joseph Walker. This information was from Deb Ashmore.
Additionally, I have John Hays wife as Sarah Bridgers. Sarah's parents were John Bridgers and Faith Ruffin (ca 1739, perhaps Northampton, NC; ca 176?). They were married ca 1758 in Northampton, NC. You can trace Faith's family line at
Waiting anxiously on your reply and hoping you are still online after such a long time.
