I inherited this profile and it popped up in my conflicts.
Family Search lists his parents as Stephen Johnson and Rachel Fox. https://www.familysearch.org/tree/person/details/GMDT-T3V
With wives Thomosina Cost and Barthenia Lindsey.
Geni has him with Bethania H. Cost / Ozley / Johnston (who has two sets of paretnts and a note that she may have been married to a "Cost." and another woman Nancy Johnson
Then there is the problem with father on Geni Drury Johnson who has two sets of parents and is not who Family Search notes as the father of Thomas.
I am not sure that either platform is correct, but it looks like a number of gedcoms have been loaded on Thomas and a lot of bad connections. Does anyone have any knowledge of this family. It is going to take a lot to sort. May be three differeint Thomas Johnsons if parents are any indication.
