The Master Surname Database (not online) (mostly burials in Alberta cemeteries) of the Alberta Genealogical Society lists these names;
Bruce DAVIS, 19 jun 1938 (Brightwood cemetery)
burial in Entwistle Cemetery Entwistle.
Bruce DAVIS, 1923 - 1929 16yrs
burial in the Brightwood cemetery Drayton Valley.
These cemeteries are about 6 or 7 Miles apart. So they seem to be two different people.
Maybe you should contact the AGS Drayton Valley Branch to see if the can get more info.
