The Master Surname Index (not online) (mostly burials in Alberta cemeteries) of the Alberta Genealogical Society lists some list some 25 Nordquist names in those four you mentioned. So I'm wodering if you have already been in touch with members of the Society to get those names. However non of the oyher names you mentioned are not in the Master Index.

For further research please contact the AGS Research Services Committee of the Edmonton Branch,

But according to a list I have "Darwell" in mentioned in 2 Local History Books "Early Days in Darwell" and "Spirit and Trails of Lac Ste Anne" they may contain something about your Nordquist. These ar Archived at the Provincial Archives.

You mentioned Certificate, but please read this from the Alberta Vital Statistics.

You can order death papers, however when ordering this you are given 2 options - the Certificate,
or a "Certified Photographic Print of the Registration of Death" which usually gives more information than that fancy Certificate.

Then I checked for a homestead for Nordquist and found 2, one for Olaf and just kity corner to his was one for a Lewis Nordquist. These would be about 10 miles north west of the cemetery. Check on this Canada National Archives and look for Western Canada Land Grants.
