James Moore, Sr., is thought to have been the son of Samuel Moore (1729-1803), of NC. He was reportedly married twice, the second time to a Mary Thompson. During the Revolution, he served as a lieutenant in the NC militia. In 1796, he was named one of the first magistrates of Grainger Co., TN, as well as the county's first coroner. He lived in E. TN, particularly in Grainger and Hawkins Cos., up through the first decade of the 1800s before removing to Preble Co., OH, where he spent the rest of his life. James was the father of eleven children: Mary; Martha (Patty); John; Samuel; Wm.; James, Jr.; Thompson; Jesse; Anderson; Alfred; and Wiley. He was schooled in the law, and his name appears frequently in the court documents of the places where he lived. He is often listed in association with surnames such as Chamberlain, Carmichael, and Thompson in the records of Grainger Co. According to some researchers, his full name was "James William Moore."
