Hello Roz,

Looking at the Dancey family tree at http://trees.ancestry.com/tree/15671340/family/familyview
I do not see an Isabella Dancey, but perhaps some people are not included. You might write a message to the owner of that tree at Ancestry.com. I believe that a son of G A Dancey is probably alive, and that his name might be Howard. He probably lives in Alberta, Canada.
