The 1790 Federal Census is entirely missing for two important Womack states, Virginia and Georgia. Additionally, a few counties from North Carolina are missing, including Caswell Co, NC, with at least two Womack families.
In 1790, there were Womacks living in Virginia, North Carolina, South Carolina, and Georgia. There were no Womacks living in Kentucky yet. Jacob Womack had lived in what became Washington Co, TN (then part of NC), but by 1790 was living in Pendleton Dist, SC. Womacks would move back into Tennessee circa 1793.
