I added a new page on Albert Arthur Wilson.
Dr. “Andrew A. Wilson” appeared in the Vancouver directory in 1910. He was living at 1086 Denman Street. It appears that this person was actually Albert Arthur Wilson, who was a physician. (He was sometimes called “A.A. Wilson” or “Arthur Wilson.”)
Note: June 18, 2020: I updated the page on Albert Arthur Wilson. I added illustrations and biographical information.
