Does anyone know if Captain Alexandre McCorkle and his wife, Mildred Welch (McCorkle) had a daughter named Sarah? She was born in 1795 and died in 1842. She married James Wilson in 1814 and they had 11 children. I have stumbled on a letter that is dated 1829 that appears to be from a brother, and the letter appears to be signed "A. B. McCorkle." Any help in piecing this together will be appreciated. The letter makes two references to facts that I know about Sarah, but I cannot connect A.B. to her.
