My name is Gene instead of George, but my great-great-great-great grandfather was George Forrest. George was living in Martin County, NC in 1790. His wife was named Winiford, and I believe her to be the daughter of Thomas Joiner/Joyner who resided in a county just north of Martin. Thomas named George Forrest as the executor of his will. George and Winiford's oldest son was named Thomas Joiner Forrest.
I don't know much else about the Forrest/Joyner connection, but I would love to talk to you about it. Thomas Joiner Forrest and his family moved to an area near the border of Haywood and Madison counties in West Tennessee in 1826. I know quite a bit about the Forrest family after they moved to Tennessee and some about the family before they moved. I know almost nothing about the Joyner's, though.
If you want to talk, my phone number is 865-386-6109. Or we can correspond by email, if you prefer.
Look forward to hearing from you.
