Hi :)
If you know that any of those relations were in the Wainwright area, you should go to the Town of Wainwright Library page and access their free online archives of the Wainwright Star Chronicle newspaper. I've found that many marriage announcements, birth announcements and obits can be found in there easily by doing a search. They have over 100 years of local history, all neatly collected and downloadable for free in one location. It is amazing!
Good Luck
:)
