well pine if ever that woman was found thanks to current uk law legally no one would be able to trace such info until the 100 year privacy time, regardless of what year it happened in the privacy law would have to be respected, after all at one time or another she was a living person entitled to privacy
What 100 year privacy time.
Here in the UK there is NO, repeat NO law of privacy.
Some in the PC brigade try to bend different laws to include privacy but it seldom works for living people and never works for dead people.
Some archives have office policies not to disclose information under 100 years old but that is completely different from there being a law to prevent it.
The reason the census was not released before 100 years is because there between 1966 and 2000 there was a statutory instrument (repealed in 2000 that prevented the early release).
Incidentally only census from 1981 onwards carried the claim that the census would confidential for 100 years
However a point that is never mentioned by those supporting the so called 100 year rule is the Census (confidentiality) Act 1991 amended the Census Act 1920 and that makes it an offence to ever release the data without there being a change of law.
Not in 100 years, not in 1,000 years not in 10,000 years, never.
