I believe the parents of the Hamilton Byers who married Nancy Townsley to be Cornelius and Susan/Susannah Byers of Wilkes Co, NC.
In 1850, Susan and her children were living in Wilkes Co, NC, with Hamilton already gone on his own with is own family, but he had been listed on the 1842 School Census records.

**America Jane 4
We know from records she also had a son named Hamilton and one named Theophilus. In 1852, a Theophilus Byers marries a Eliza Crawford/Cranford in Rowan Co.
Again, I know there was another Hamilton around BUT why would there randomly be a Theophilus living there a few years after Hamilton got married? It seems to me more than a coincidence.
