I have Elizabeth's parents as Spilsby
Tribble and an Unknown Mary.
Spilsby's parents were
Shadrack Tribble and Elizabeth
Coleman.
Shadrack's parents were George
Tribble and Dinah Esther
Meadors.
Spilsby Cocke's grandmother was a Whitehead...but I don't have any other Whiteheads in the line.
I also don't show Benjamin Franklin
Tribble but there were several families descended from George. Most of his children were biblical names like
Shadrack and
Absolum.
It would have had to be one of Shadrack's grand children since he died in 1759, before Franklin became a household name.
