In 1911 still the same three peopls, though moved to St Leonard Dale Cottage Clewer Green, Clewer Within, Berks.  But the census sheet shows that they had had three children of whom two had died.  So now to find the other two.

I can only find one more child, born in 1884.  Perhaps the last oen did not survive long enough to be registered?
