Personally I probably wouldn’t find it useful. But I’d say that about the whole advanced search. I’ve never found a need for it.
But for those who do, I’m happy to investigate this. It doesn’t sound too problematic at first thought. But a couple questions:
- Would it also need +/- 5, 10 yrs etc as well?
- Would you want to do BEFORE and AFTER together, or just one at a time?
Regarding your primary requirement, doesn’t Resources > UK 1939 Register do that for you? It looks at anyone alive at the time.
