The finding aids and indexes (not online) of the
Alberta Genealogical Society lists these three;
KANOUSE, Fred (
HAA.) can be found in the book index of "History of
Alberta".
KANOUSE, Fred H. 18 Jun 1908 - 18 Jan 1980, (more info may be in the file 'Strays Canada Wide')
KANOUSE, Frederick A. died 21 Dec 1922 (index of the Ft
Macleod Obits).
I am not familiar with a St Mary River, nor of
Kanouse Mines in the Edmonton Area. However is may be in the area 300 miles south, and the Ft
Macleod area.
You may want to contact the AGS Edmonton Branch Research Group that has access to the the above sources.
