I descend from James Sr, apparently through his son William and wife Esther McMillin (sister of Eleanor McMillin and John L. McMillin, father of Thomas's wife Elizabeth).
Two of Thomas's descendants, one through Elizabeth McMillin, and one through Syrena Emmerson, have tested their DNA. In all about a dozen of us trace to James Sr (two possibly to a brother or first cousin of James Sr).
I also descend from Malinda Mathis (married name Stagner), sister of Leonard Mathis, William Mathis, Thomas Mathis, etc.
