Did you find out the information that you were looking for? Eliza Chynoweth was my Great Aunt, my Grandfathers sister. William's sister also married a Chynoweth. They all lived around the Wainwright area, I think it was around 1914-15 that they went West.
John Thomas (Jack) CHYNOWETH (1871:04:12 - 1944:04:28)
Md Effa May Eliza COOPER (1884:07:23 - 1974:11:12)
Eliza Jane (Jen) CHYNOWETH (1879:07:01 - 1952:06:07)
Md William Leonard Norman COOPER (1880:04:21 - 1962:12:14)
I hope this helps.
