Hi, sorry for my english, I have Duchain in my ancestry and I have one who went in Saskatchewan. Maybe I will have something for you. My mother told me that 2 uncle went there and one get married with a women from there. She lost her first usband because of ward but he came back 15 years later. one was Ernest Duchaine (prêtre) and the other was maybe Eugène Duchaine but not sure, i ask my mother.
