Hi Nick,
Catherine (Layfield) Eyles died June 20, 1890 at New Westminster, British Columbia. Her death does not seem to be registered in the BC Archives records but there is a picture of her grave on Ancestry. Her daughter and my great grandmother Maria Eyles married David Dixon Burnett at Mattawa, Ontario,September 19, 1885, so the Eyles family had not been in British Columbia for long before Catherine died. I have quite a bit about the Burnett/Eyles/Layfield families which I will try to send you before Christmas. Catherine's sister Elizabeth Layfield, born march 26, 1823, is also part of my family.
