There is a book that is available online from the University of Calgary called "St. Lina and Surrounding Area" and it's about St. Lina, Alberta and the original families who lived there
(

I checked, and your grandfather, Evan MacPherson is mentioned in the book - note: some of these links are long and will wrap, so you may need to cut and paste them into your browser:

http://www.archives.ca/02/02011102_e.html and found Evan McPherson (his name is spelled "Mc" instead of "Mac" in the database):
