Have you contacted Candace Teal Gravelle (TealTree@attbi.com)? - she is a direct descendant of William Teal Jr. and Sarah Dupree by their son, Joshua Teal and his wife Mary Polly Wallace.
My line is most likely connected, but we are not sure how. I am descended from Elizabeth Teal (1796-1884) and Lacy Hattaway, who were also probably from Pitt and Anson Co., NC. They married in 1825 in Jasper Co., GA, then moved on to Campbell Co., GA by 1830, where Joshua Teal also was living. Many of their descendants also moved to the Tallapoosa/Cleburne/Randolph Co., AL area. Lacy and Elizabeth are connected in land records to George Washington "Wash" Teal, son of Emanuel Teal Jr. Lacy and Elizabeth's oldest son was also named Emanuel.
I have collected quite a bit of information over the years, hoping to connect my Elizabeth Teal Hattaway to either William Teal Jr., Bradberry Teal, Loderick Teal, or Emanuel Teal Jr. I would be more than happy to share!
