I have searched the 1921 census and I did find a W.R. McFarlane who was married and seemed to be about the correct age, which I don't have. He was a lodger and no Cora with him. He always seemed to use the initials W.R. and I don't know what they stand for, although I am guessing William. I also don't know what the V.C. stands for with Cora. I don't know where they were married but most of Cora's family seems to have west. Having said that, the W.R. that I found was in Ontario in 1921 if that is him. He is Presbyterian on the census and Cora was known to be Presbyterian.
Thanks for your suggestions
