James I saw your posting concerning your Thomas Jefferson Adams, born January 3, 1849. First is this birth date set in stone? If not please flex your thinking and consider what the 1850 and 1860, Pittsylvania County Va. census says about "Thomas Adams."
1850 Pitts. Co., Va. states on 11 Sep 1850, page 189B, Northern Dist.,a 7/12 month old son named Thomas is living in the household of Robert Adams age 47, b. Va., Ann Bailey 35 William 17, John 14, Robert 12, Elizabeth 11, Lucinda 8, Thomas 7/12.The question is whether Ann Bailey the mother or the person replacing the true mother who might of died in child birth.
A better choice might be 1860 Census,Pitts. Co., Va., page 565A, Souther Dist., 15 Oct 1860.Please be flexible with your dates. You claim your Thomas Jefferson had a son named John and one named James.
This census list a head of household Thomas J. Adams 28, b. Va., wife Mary 21, "JAMES" 4, B. va.,"JOHN" 2/12, B. Va. and a sister Martha 1, b. Va.
How many Thomas J. Adams would you quess was living in Pitts. Co. with two sons named John and James?
First thing you learn after a few years of genealogy researching is most of the information obtained from other people are wrong.
I feel I have giving you good clues as to where to start in your search of your Thomas Jefferson.
