NWMP Inspector Begin was in Dyea in 1897. He was born on this day, February 15, 1856 in Quebec and spent several years working on steamboats on the St. Lawrence River and then served in the militia for three years before joining the NWMP in 1885. He served in several provinces before coming to the Yukon. In 1891 he married to Alexina Chartrand and in 1893 had a daughter, Renalde, and then two sons: Francoise Begin born in 1894, and Jean Berchmans Begin, born in 1897. His family must have lived in a larger community, not Dyea, certainly, judging from photos of the family.
From here he went to South Africa and later served in the Great War – a euphemism for WW1 which was big but not all that great. In 1929 he moved to Atlanta Georgia where he died.
The photos of Captain Begin were small and grainy but the fellow on the horse in this poster looks like he posed for this.
