Hi Silvercraig,
Looking at the 1891 Canadian Census - can see a John, Margaret and Hellen in Deux Montagnes district. This John was born Quebec 1857 (parents - Scotland), Margaret 1863 (Father Scotland and Mother - Quebec) and Hellen born in Quebec 1889. Is this the one ?
In 1911 this family (with one more child Donald born 1894 Quebec) were at Jay Street, Vankleek Hill, Ontario
John Oswald Aged 54 years was a farmer. Born Quebec. Margaret Oswald 49
Helen Oswald 20 and Donald Oswald 17
Cam Miller 12 Nephew.
