I don't know how familiar you are with the history of the area, but the date coincides with the start of the pulp and paper industry in the St. Maurice valley. Laurentide Paper Company was started in Grand'mere and engineers were enticed to the area by the offer of jobs, low cost housing, private school for their children and company-sponsored medical care and hospital. The "company" took excellent care of their employees for at least the next 60 years. I am a child of one of those
English immigrants who grew up in Grand'mere in the 40's and 50's.
