For what it's worth, I think.... Shadrach Mims and Elizabeth Kirkham were the parents of Sally Mims who m William Jemison. They were also the parents of David Mims who m Sophie Moles Addison. Their parents died in 1804 and 1814 respectively, David being about 7 years old and Sally was already married and 29 years old. It is natural to believe that she raised her brother, David, who with William Jemison as a stepfather figure, named one of his children, William Jemison Mims. Linda in KCMO
