Hello - you make a good point.No, I am not sure.I found Canada census information pointing to a birth, age, etc.that could be her.
Denyse DesJardins married Hercules Scott Porteous (son of a wealthy Scottish landed gentry family)in Denver, Colorado during the gold rush and cattle industry days of the late 1880s.
It is quite possible that she concocted a "story" of her parentage.She was a central figure in a controversial marriage which resulted in a lawsuit.In a newspaper article, she states she was previously married (don't know if she was divorced or widowed).She is buried in Vancouver, British Columbia where she and Hercules moved to after the Denver "scandal". But before they settled in Vancouver, they spent some time back in Scotland/England with the Porteous family.
It is a fascinating story.As usual it was the media (newspapers) of that time that almost ruined them.Their "legend" lived on years later in the form of an adopted step daughter from Hercules Porteous' first wife who came back seeking her fortune from the rumoured death of Hercules in Russia or India!
If you find anything else, I really look forward to hearing about it!
