As I mentioned I am not a descendant of Samuel or his father James Jr., and I'm relatively sure I don't have all of Samuel's and Elizabeth's family. My Alexander line comes through one of Samuel's uncles--either Matthew or William, both of whom migrated to western KY with their father in law (married sisters) and his family shortly after 1790.
The children whom I have for Samuel and Elizabeth are: John Hinto, born December 25, 1813 (exact birth date from a descendant); probably Robert C., born about 1817; Sarah, born April 1, 1820 (exact birth date from a descendant); Margaret, born about 1822; Elizabeth E, born about 1828; Louisa E., born about 1829; Samuel Logan, born about 1831. I have marriages for all and children and other information for John Hinton and Samuel Logan and, if my addresses are still valid, can put you in contact with descendants of Robert C. and Sarah. I also have quite a bit of data on Samuel's brothers and one sister, and a descendant, whom my wife and I know well, has much more on them.
Samuel's father James Jr. remained around Spartanburg, SC, when his brothers left; however, at some point, Samuel went to visit or live with one of the uncles. William Alexander, who was either William's or Matthew's son, married Hettie Hinton in Logan County, Ky, February 1806, and, then, Samuel Alexander married Elizabeth Hinton April 1808 in Logan County. Around 1810 or 1812, Samuel and Elizabeth joined Samuel's family that had just come to Roane County, TN, from SC. The Hinton women may have been sisters, and, if so, their father may have been John Hinton, for whose will Matthew Alexander served as a witness.
We should probably continue by e-mail instead of posting long items of little interest to any reader but you and me. I'm interested in anything you know about the Hintons and would like to get a couple of descendant generations on all three of the sisters you have.
