There was a James MacKay, listed as "merchant in Glasgow" who married Mary Gunn in Arnaboll on 6th May 1815.
While Arnaboll is now almost inaccessible, the path from Eriboll to Arnaboll still exists and could be driven by car into the 1990s, although you would need a quad bike now.
"Your" James would be 32, so he might have retained some connection to his place of origin and married someone known to his family.
