Do you already have the BC death registrations for these two? Obituaries are really hit and miss and sometimes hard to track down if they were placed in smaller, community newspapers. Based on my experience, published obits for us common folk weren't very popular in Vancouver until the late 1950s onwards. The BC registrations contain quite a bit of information so depending on what you are looking for, you might find it there.
If you don't have the registrations, please let me know and I will look them up for you.
