Wilbur was born ca. 1896 in Reston, Manitoba. It is possible that he and his brother Wesley were in fact twins. He came over the Edson Trail in 1914 with his father, Alfred Wesley Harper, and two brothers, Robert Lester and Wesley. The men settled in the Pouce Coupe area; Wilbur’s homestead was located at NW 4-79-15-W6. On his homestead record, it shows that he was in military service while proving up.
