There is no doubt that Susan Bigby is the sister of James Bigby Jr.. She is not the daughter. I saw on a sight where a Mary Hicks was married to a Bigby but a first name was not given. James Bigby Jr.'s mother was Elizabeth Hicks, daughter of Nathan Hicks and Nancy Broom, daughter of Chief Broom of Broomtown a Cherokee town. Chief Charles R. Hicks, a son of Nathan and Nancy Hicks should be a brother of Elizabeth and Mary Hicks and Uncle to Susan Bigby. Oh yeah it listed Nathan and Nancy Hicks as the parents of Mary Hicks so she is a sister to Charles and Elizabeth. The answer to our mystery is in S.C. or Ga. where Nathan or Nancy were either married or born. Thanks for all your help. Keep in touch! Ronnie Sellers.
