Thank you Debbie for directories and Lynwen for more on Albert.
Concerning Alice Clara Penny: in a letter (1955) she says that her husband, Will Craig, was born and raised in Scotland and went to Canada in 1910, stayed 3 years and then went home to see his folks, came back to Canada as a farmer and made it his home. He made a further trip to see his father, presumably to Scotland. The letter of 1995 was sent, though, from 208C East Maple Street, Glendale, 5, California! She also gives her age as 60 on 3 August 1954 with Allan being 19 and Alma 15 on her birthday. The 1911 census entry (found by Debbie) gives that Clara's birthdate as June 1894 so she seems to be a different Clara Penny.
The younger children are still a bit of a mystery. My thought was that they may have been sent sent to Canada as Home Children but I couldn't find any evidence.
