Yes, Cecil was one of theirs and is with Lulu and Vera in 1911.
There other son Frederick is with his mother in 1911 so as far as I know the children are
Lulu, Samuel, Vera, Cecil, Frederick and Victor.
Good to have their 1906 address and to know where Samuel was employed, at least he had a job in 1906. How did you discover the address mowsehowse?
Finding him in 1911 seems a lost cause and I'm puzzled why we can't find a death record, any clues?
