Thomas Williamson m. Keziah Broyles

I am new to genealogy and could use some help!I have family history provided by ggrandfather which traces back to Jeremiah Williamson of Green Co. TN.I am searching for his parents.I have found some info that indicates Thomas Williamson and Keziah Broyles are his parents but no proof.I also can not find anything on the Williamson side past Thomas (may have been a Reverend).

I will be happy to share any of my info if you can help!
Thanks
Connie
