I received an email from a researcher of the Harkins family who had found a connection to the Terry Family. She gave me the following information
In the 1850 census in Murray Co, GA, next door to Lewis Terry is the Harkins family. Nancy Terry, believed to be the daughter of George Terry, married Asbury Harkins. Asbury's brother, Tilman married Jane Elizabeth Terry. She was on the other side of the houses, in the
The family story is that Elizabeth and Nancy are sisters. When looking into application for Cherokee roll citizenship, both children of Nancy and Elizabeth list the same two people, one specifically listed as a grandmother. This makes them at least first cousins.
In a letter of information from Sarah Chastain, Tilman's sister, she states that Nancy D Pierce (Nancy Dovina Harkins Pierce, daughter of Tilman) is the 'daughter of Jane Harkins (nee Terry) whose great grandmother Nancy C Keith and who was the descendant of John Keith who
were Cherokee Indian by blood.' and continues 'said Nancy D Pierce's grandparent was Polly Smith, who was also Cherokee Indian by blood.'
On Nancy's application she states she is related to John Keith and 'Polly Smith, my grandmother.'
From information on your site I do not see Polly Smith or any Keiths. These Cherokee relatives must be on the Terry side as Sarah Harkins Chastain stated has no interest in the application. Perhaps their mother?
