I do not believe this is the correct Miller family.

Amanda was Leah Amanda Miller and she married my GG GF Jesse D. Brown in 1857. He was killed in Civil war and she later married John Jacobs.

This Amanda did say b. GA and later says AL.
Penelope Ann married a Barnes so she was not the Elizabeth.

I do not find any Millers in Dale Co. 1850 with Amanda and Elizabeth. It is likey this Miller family was not in Dale Co. at that time.

Thanks
