I'm trying to trace a descendant of these Tullos lines and there are errors in the connections here on Geni. For one thing, the parents of this John are listed as Richard Templeton Tullos and Elizabeth Temple. But those are also listed as the parents of his wife Elizabeth, meaning he married sister and had a family with her.
Elizabeth Bunnell (Tullos)
Gender: Female
Birth: December 06, 1731
Northumberland County, Virginia, British Colonial America
Death: 1790 (58-59)
Effingham County, Georgia, United States
Immediate Family:
Daughter of Richard Templeton Tullos and Elizabeth Tullos (Temple)
Wife of John Tullos and NN Bunnell
I'm pretty sure that must an error.
