Hi Cecile,
I cannot find the family on the 1911 census.  There is a James Jones married in Kitchener, Waterloo,Ontario.  
James Jones, born Liverpool, abt. 1898, age 21
Parents - Thos. Jones & Isabella Lowe
Spouse - Daisy Ford, born England, abt. 1900, age 19
Parents - Robert Ford & Helen Ellaway
Marriage Date -   30 Aug 1919
I will check in Ontario and see if there is anything else on the rest of the family.
