The following announcement was written by the folks at Findmypast:
Thanks to the work of the 1939 Register team, we’ve been able to successfully match and open over 60,000 more records that were previously closed, and they’re all available to explore right now. If you have tried unsuccessfully to find a family member in the Register who died after 1991, it may be worth trying another search.
Find out what your ancestors were doing on the eve of WW2 by searching the 1939 Register, available to search online only on Findmypast. Discover exactly what they did for a living, maps of where they lived and even who their neighbours were. Or click on the address tab to search for your own address, or an address you know, to see who was living there in September 1939. Then you can put it all in context. Read newspaper articles and see photographs from the era.
