I believe I can shed more light on the Tapscott/Baynes connection. In searching records of my ancestor George Lea(Lee) and his mother, Mary Lea(Lee) of Haywood I found court transcriptions of a competency hearing of Nancy Tapscott, who was 66 and blind. Miss Tapscotts brothers had died and from what I could gather one of her nephews was trying to take her "property", 8 slaves. Dr George Lee testified she was not competent, however Mary Lee (his mother) testified she was. Both Lees verify having lived many years as a neighbor of Miss Tapscott in Caswell Co, NC before becoming neighbors again in Haywood, TN. Mary Lee verifies that the Mr Baynes whom Miss Tapscott lives with and had chosen to handle her business was her (Mary Lee's) son-in-law, therefore, his wife, Sarah, must be her daughter.
I have the document and my transcription linked to Mary and George in my tree. The file is under "George Lee" in Haywood Cty rather than Nancy Tapscott.
Previously I did not know Mary Lea's spouses name and am interesting in any source documents indicating she was the Mary "Polly" Swift who married John Lea. Some notes indicate this Mary died and was buried in Caswell Co, NC but my Mary Lea is buried in Concord Cemetery, Gates, TN along with her sons Thomas Fletcher and Dr. George Washington Lee. Considering the Tapscott connection I feel certain this is the same Mary.
