Henderson’s Greater Vancouver City Directory, 1917, page 657 [edited image].
I added a new page on Robert Fenton Mather
. He was the manager of Davis Hartney and Company, which was a firm of electricians with offices at 1150 Hamilton Street.
He lived at 1934 Barclay Street in 1917 and probably 1918 (although the streets directory listed him at 1940 Barclay Street).
