I have some information on a Dennis Lynch, who was a Park Warden in Waterton Lakes National Park ca. 1919-1924 and Jasper N.P. 1924 to about 1928. at which point he seems to have moved to Banff N.P. and worked for the park until sometime in the 1940's or 1950's (but not as a park warden). This D. lynch also enlisted in the 13th Canadian Mounted Rifles in Feb. of 1915 (Regimental # 552068, DOB 1 Jan. 1884, Age 31, Born in New Brunswick, Single, Occupation: Teamster. Address: Pincher Creek). Dennis Lynch & family also show up in the 1901 and 1906 census returns, living in Pincher Creek, Ab.
