The BC Archives is full of people you need. The couple's marriage record is available to purchase on-line as it is one of the few now digitally scanned in . Looked upo the death index and found Percy Charles in Kamloops and there seems to be a son ( has Loat as a middle name) , maybe a brother of Charles and then there seems to a Cora dying in Victoria. These are all available on-line to anyone. I have not checked the BC Cemetary site for the burial sites but you can do that yourself. Do you need the site addresses?
