http://www.bac-lac.gc.ca/eng/discover/military-heritage/first-world-war/personnel-records/Pages/item.aspx?IdNumber=72837The above is a link for the WW1 records for a Lloyd Brydon. He lists his next of kin as his aunt, Mrs. W. Fraser of Melfort.
It looks like he puts his birthdate as 16 Jan 1890, but after a ton of searching, it is really 1896. Either he didn't press hard enough on the pen, or the top tail of the six has faded away. Anyways, he is the son of Bridget's sister, Jenny/Jane, who married Walter Brydon.
Lloyd was actually born in Ontario, same place that William and Bridget were in 1906. Lloyd's mother didn't die until the 1950's, (and his father left the family when he was young), so I'm not sure why he had his paychecks go to his Aunt Bridget (if you open his digital file at the above link) you will see her listed on multiple pages).
He was living in Winnipeg on the 1921 census, and moved to Illinois in 1925. I'm guessing that Bridget was visiting him when she died in Winnipeg in 1923.
I still can't find them (William and Bridget) in 1916, but the WW1 records state she was in Melfort. Going through the 1921 census page by page, I finally found them, mistranscribed as surname Frason. They are on MacLeod Ave, Melfort, William is a merchant. If searching under Frason does not work, follow this:

Saskatchewan
Prince Albert
Sub-District 50 - Melfort (Town)

Also, I found the Melfort newspapers online, but so far for only the WW1 years at
