I think that your Polly (Mary Ann) Adams b. 4/19/1828 is the same one that married William Gann in Fayette county, GA on 4/30/1844. Wm Gann died soon after & Polly's family moved to AL around Talladega county. It is very possible that Polly went on to AL to be near her family. The Adams family later moved to MS & then to Arkansas were some of them can still be found in Independence county. Good Luck.
