I'd be quite happy waiting for 100 year gap to maintain confidentiality if this happened in every other sphere of life!
I remarried four years ago. Type in my name on ancestry and there I am - under the marriages between 1984-2004. If you're interested you can send to Southport for a copy of my marriage certificate, which has my current address, my age, my occupation etc. Now if the government thinks it's OK to put all that info into the public domain, it beats me why the address my grandmother lived at in 1911 should be seen as so sensitive!!
You could think of a dozen other examples of how all our details are in the public domain for those prepared to look. Very few details from 1911 will be relevant today - there's just no logic here, at all.
