This is awesome information. I look fwd to see what you find in the DNA comparison.
In 1850, Daniel was married and would have been off on his own.
Here is my information.
I was born in Odessa, TX in 1953 to Herbert b. 1922 in Oklahoma. His father was Dempsey b. 1875 in Henry Co, TN. His father was James C. b. 1855 in TN (probably in Henry). James' dad was Daniel b. 1826. I hired a genealogist who said that she felt sure, from what she could find, that Thomas was Daniel's father but couldn't produce any hard evidence. This is as far as I could get.
