Hi Gregor: Is it possible your Amy MacGregor would have been buried her maiden name. Have found some of the Matthews as followed: James Hubert d. 1982, buried St. Vital Cemetery, Winnipeg, Manitoba Joseph L. d. 1988 buried Broookside Cemetery. The burial order, plot numbers, etc. are given plus date of death and burial on-line, City of Winnipeg Cemetery pages. I did not check out MacGregor/McGregor burials. Is it possible your Amy retired to West Coast or else left Manitoba to live with family? Not finding her in the Municipal Cemeteries does not mean she isn't buried in Winnipeg - lots of other Cemeteries. A lot of people from Manitoba did and still do retired to British Columbia - many to Victoria out there. You could check deaths in the BC Vital Stats, but not sure if they have the more recent ones? Good luck. Lauraine (Smith) Syrnick
