I wonder if you have come up with parents for Thos. Jefferson Aker, from Wythe Co., VA? There are two different Aker families in that country at that time, one and by far the largest from what would be Smyth Co., VA today; the other, much smaller Aker family from just east of Wytheville, Wythe County's county seat. The only child of this latter family to remain in Virginia was Michael Aker, sometimes spelled Akers, who sired a large local family. The other family members went on to Ohio and Indiana. The 1818 birthdate makes this Thos. Jeff. Aker of interest to my research, which concerns both Aker families.
