Howdy Kathryn, I have Elijah Alexander born 1760 in Mecklenburg, N.C. died 1850 in Giles County, TN. His father was Captain William Alexander born about 1730. William served under Colonel Wade Hampton in South Carolina. I do not know who William Alexander's parents or wife was.
Elijah's sister Ruth married Joseph James Clark on April 2, 1789 in Mecklenburg County, N.C.Her children with Joseph Clark were : Rebecca, Mary, Williams, Susannah, Margaret, James A., Josiah G., Elijah C., Joseph H. Clark.
That's all I have on William, Ruth and Elijah. I'm a east Tennessee Alexander kin.
Good searching, Andrew Dennis (Alexander) Faircloth email@example.com
