I am researching his brother Zachariah Roberts, I know their Father is Edward Roberts Sr. he appears in the 1840 and 1830 census of Carroll County Tennessee. Many of the trees on line have their father as Edward Roberts and mother Susan Ballard, but I believe this to be incorrect, I have read they had no children and this Edward Roberts is Roane county tennessee all his life. I have found that Edward and Zachariah were born in "Indian Lands" Tennessee. I believe Edward Sr. is from North Carolina or South Carolina. I am stuck and have been for about a year. Hope this helps you out.
