I called the High River Town Office today and asked for the dates for the burials for Mabel and William Dancey. They have the dates the plots were purchased which might help -
Mabels plot was purchased 2, 3, 1958 (March 2 or Feb 3, 1958) and Williams was purchased September 29, 1954. These dates should help narrow down the dates to look in the newspapers for obits - the newspaper for High River is the High River Times (it was around back then as well). Most newspapers for southern Alberta are archived in the Glenbow Museum in Calgary and there is a major collection of newspapers for all over Alberta in Edmonton. I would think that if you looked in the Huxley paper near the time of death for Glen you would find an obit or at least a mention. The newspapers were very thorough in their reporting of WW2 deaths of soldiers from local families.

I live in Calgary and the next time I am at the Glenbow I will check on the obits in High River. I have no idea how soon that will be though.
