MACPHERSON in Ballon, Golspie

I am looking for are the MacPherson family. George MacPherson married Katherine Sutherland in 1751. He was from Ballon, Golspie. She was was from Sallach, Golspie. She was obviously local, but where did he come from. Could he be one of the MacPhersons who came from the far north of the county. I am also interested in what his occupation was. Their son Donald born 1762 was my 3xg/grandfather who after he left the Sutherland Fencibles became a farmer in Marykirk near Montrose.
Welcome any information.
