Royal Smith's mother was Dorothy Smith so that means the the Elizabeth Smith you are seeking is Royal's sister and her mother is Dorothy Smith. The 1921 census shows Elizabeth's mother (and Royal's mother) Dorothy living with her son Royal Smith (who raised my father from 1921 on). Note the 1901 census also show Royal living in Kenora (in the 1881 census Royal is 8 and still in Buckingham) Is it possible that Elizabeth lived with her mother in Kenora 1908 rather than her grandmother? If so then she likely lived with Royal Smith as well. They were still living in Kenora then likely at 336 - 8 Ave South (in Southward) The might have been the address she'd been at as they had lived there a long time. Royal and his family (including my father) moved to Longbow likely around 1930 if not before (but after 1921). If she did live with her grandmother then this may not be helpful. Attached is the JPG.
