I have absolutely no idea if this is the same man, however it could be a lead worth tracing:

Archibald McRobert m. Mariah Blackbourne/Blackburn in Madison Co, AL 11 August 1824

He must have died very quickly afterward, because she remarried in April to Edward Bressie VAUGHAN.

The VAUGHANs and BLACKBOURNs were all from VA (Mecklenburg Co. area), and had not been in AL long at this time.

Hope this is helpful.
