A query about Irish boundaries had me thinking and I recalled seeing a site where historic maps had been scanned to create a project that tracked the various boundaries of the UK over time. This project created a wonderful resource for family historians called A Vision of Britain through time.
The site describes itself as "A vision of Britain between 1801 and 2001. Including maps, statistical trends and historical descriptions". It is a fascinating resource and particularly helpful in tracking down places that were near various boundaries. You can enter a placename and it will take you to a page where you can view all the maps in its collection for that place. eg: Stanstead Mountfitchet.
