Just spotted this: Gleaner Extracts: “02-18-1872 Helen Walker, Widow of the late Francis Sherriff, died at Muirton, East Lothian, Scotland. Aged 85 years.” http://www.rootsweb.ancestry.com/~qchuntin/gleaner/1872.htm

It's from the Huntingdon Gleaner in Huntingdon,Quebec, where Francis & Helen's 6th son Francis Walker Shirriff became a doctor. I know a lot about him and his descendants in Canada if anyone's interested.
