Yes i to noticed a gap in the children but have been unable to find anymore. On he 61 census William and Selena have a 6week old baby 'boarding' with them named William born in Douglas. I have been trying to find who it might belong to in the hope it may be a clue as to williams parents. I would have thought if it was a relative though it would say nephew of something. I know it is definately not theirs as Selena had just had Rebecca.
