I do not have proof of the parents of Mary Rawls Busby.I have wondered if she is related in some way to Josph Rawls b 20 Oct 1764 and his wife Sophia Kinsler. I have direct Kinsler ancestors. I only have the names of three children for Joseph Rawls (one son and two daughters.) Both of the daughters have the first name of Mary but went by their second names. I am sure there must have been other children. I do know that the Rawls family is very closely tied to several of my ancestral lines. Please email me at email@example.com or at firstname.lastname@example.org. I will be happy to exchange information. I think we probably have several lines in common.
