Hello, I've just seen a query re using historic maps. The local authority where I live in West Yorkshire has a lot of historic maps on its website - www.calderdale.gov.uk and choose the Online Services tab - if anyone has ancestors from the Halifax/Brighouse/Todmoden/Hebden Bridge/Elland areas you might find interesting information there - can add different layers etc. I just mention this because it might be worth looking up local authority web-sites now for any area - local authorities are adding more and more information about their areas all the time. Good luck! Margaret
