Looking for Dube Family Lived IN Canada Then N H

I am trying to find the Dube family, lived in Canada, then Mary Ange Dube, married Leo Holden, and lived in New Hampshire. I have no other info on mother/father of Mary, My mother Nancy Holden Woodbury, was Marys daughter. I do know that Mary was born in 1904 and died at the age of 37,1944. Mary Dubes parants were origanally from overseas. I would like to hear from anyone that has a name or anything else. I am doing this for my mother who never got to know her own mother. thanks for any infor you may have
