Obviously we are looking within the Pontefract registration district, not just Pontefract as a town, which could well be a much larger area, also bearing in mind that
Annie would be 7 or 8.
they may well have moved somewhere else.
I'd be happy to give it a try, can you provide the mother's name from the birth certificate and the address where her birth was registered, so trying to find more of a family unit rather than just one little girl, and we'll start over again.
Have you now decided that Annie is this single child, rather than the twin as previously searched for?
