I agrre with Mr. Pratt. Lewis born 1785, Richard born 1788, are Sons of Morris Adkins and not Elijah Adkins. Please refer to the 1810 Grainger Co., TN census. Richard Adkins was appointed guardian of Stephen Adkin's Children in Grainger Co., TN, sometime between 1810 to 1815, Stephen I believe was a Brother to Richard and Lewis Adkins.
Elijah Adkins Jr. born 1791 is a Son of Elijah Adkins and Nancy Hunter, he married Mary Lamar. They are in the 1840 Anderson Co., TN census, only Mary and the Children were found in the 1850 census of Anderson Co., TN.
I belive the Nancy Adkins listed is actually the Daughter of Stephen Adkins, she married Archibald Mullins.According to Godspeed's Sketch of Archibald Mullins, she must a Niece to Richard and Lewis Adkins and not their Sister.
