Alexander "Sandy" Sutherland, was born on the 16th of August 1900, in Forres, Morayshire, Scotland. It seems he came from a family of 10 children that moved to Canada. His parents were John Sutherland (b. 1855) and Jane Naughy Bain (b. 1866).
I don't believe that Sandy is the Somerton Man, but he does share many facial features. It may be worth following up on him.
The photo looks like it was taken in his early teens.
