In The Trails Northwest: a history of the district of Barrhead Alberta, 1867-1967, pg. there's a note about James Dance who came from England with his wife and 4 sons about 1908.

Also see The Golden Years
http://www.ourroots.ca/e/toc.aspx?id=4191 where pg. 155 mentions James Dance reaching the age of 99.

I take it that Beatrice was James Dance's second wife.

You can find Beatrice in the 1881 census for England.
