I am a gg grandaughter of Nancy Brightwell born 1816 to 1820 in South Carolina per 1850 & 1860 Stewart Co., GA FC. Living next door to brother William. She married 1835 in Stewart Co. to Henry Mitchell. Children are John N. and William Henry Mitchell. Can anyone please help me find parents for her. Believe her father to be William. Known siblings are William, Mary, L. Reynolds, and John J. I have been at a complete standstill for years.
