I think we need more source material to make a case.
Mary Hanchy was married to a man named John Blanton, but was it this John Blanton? John Blanton
The marriage license was issued Oct. 1, 1808 when the John above would have been 12.
"North Carolina Marriages, 1759-1979", database, FamilySearch (https://familysearch.org/ark:/61903/1:1:F8YW-258 : 14 February 2020), Mary Hanchy in entry for John Blanan or Blanton, 1808.
Two sites on a John Blanton and Mary Hanchy indicate to me that it may be a different John Blanton married to Mary.

No children attached to this supposed union. Any thoughts appreciated.
