Daughter of Abigail and David Hall, mentioned in a letter from Abigail to Frances Seward, Nov. 1, 1856 (note discrepancy on dates- Abigail mentions being the mother of a baby AND 5 other children, but Martha wasn't born until a month later according to her headstone- maybe she referred to the difficulty of carying this baby?) "You have the clair-voyance of experience & will understand, without more detail, that the Mother of a baby & five other children , who is also a housekeeper & a hostess, must sometimes have engrossments that cannot be postponed, even for writing of a short letter." Nov. 1, 1856
