DOLMANS IN CANADA

If anyone reading this knows of a Dolman Family living in Saskatchewan, Canada in early 1900's I would appreciate hearing from you. I am looking for Margaret Wilson b. 1877 in Montgomeryshire Wales and married a Dolman in either Canada or Montana State USA about 1905-10. She had at least two children Mary and a son called "Beaver". I am trying to trace family of Grandma Laura, age 96 who remembers aunt Margaret but cannot remember her husbands first name. She thinks he may have died fairly young
