well, some assumptions might be made about Caroline - most likely aged twixt 15 and 30, linked to Surrey and/or West Ham...
Theres a candidate in Plaistow, West Ham in the 1901 census born c1879, (K)naresboro', Yorks.
By 1910 she could well have been in Service in Surrey - people were very mobile it seems, and of course the census being only a snapshot on one night in 10 years ....

Child Caroline Knaresbro' 9a 104
Hmmm, just extended marriage search done earlier back as afar as 1901, and this appeared - most prob the girl in the 1901 census then. (In fact the FREE INDEX shows her as Mrs Walter Thorp, born c1879, Naisboro, Yorks)
Marriages Dec 1902
CHILDS Caroline W. Ham 4a 494
Rayner Thomas James W. Ham 4a 494
Thorp Walter Frederick W. Ham 4a 494
Wright Edith Frances W. Ham 4a 494
Turning to Edward Cyril - I had wondered if he took a stepfather's name, as I too can't see him on the 1911 FREE INDEX.
