You're welcome

Just to round off, she seems to have been calling herself Daisy in the 1911 census of Canada, when she and Christopher were in New Westminster, B.C. with two children. They had sailed from England on 2 April 1911 so will just have missed the English 1911 census which was taken on the night of 2 April!
Christopher's birth name (registered 1872, Isle of Wight) was actually Christopher Alexander Dennes rather than Dennis, though the family seem to have changed usage to Dennis in due course (they were still Dennes in the 1911 migration and Canadian census records but both died in B.C. as Dennis).
I can't see a marriage for them. Christopher in fact seems to have married a Susan Smart in the Isle of Wight in 1893 so the emigration to Canada may have been an escape route from a marriage which had broken down.
