I don't have access to Scot 1911 If she was missing from 1911 you could 'suppose' she came to Canada and work on that family?
She might have even come 1906 or 1908 - census seem to
always be wrong
besides her marriage do you have any other papers with info on her - death (you'd have to pay Reg Gen) or obit - funeral home - kids marriages etc etc
