Hey Joe,
Maybe a quick phone call to Kerry or Chris or Donald would answer some questions. will maybe try the email addresses I have when I get home from an errand (I'll send you a Carbon copy as well)....it is only 11:07 a.m. there in British Columbia December 3...so the chances of you waking them up are slim.
Unfortunately Saskatchewan is a fairly young province (only 100 years old) and records aren't released to the public until at least 90 years have passed. Your best bet would be to give a quick phone call to these people to see if they are family. The McGourlick family kept a low profile here in Canada (no WW1 vets, no obituaries, etc.) that I can see at first glance. As well there are only 3 listed in all of Canada, so the margin of error is slim or some married and have different last names.
Hope this helps....let me know if you do call...would like to see how this pans out.
Got to run, be back in a bit
Jeff
