Following their undignified and speedy removal last year, they have, as expected, been returned to us on the state-run site with the 100-year (births 1864–1914), 75-year (marriages 1845/1864–1939) and 50-year (deaths 1864–1864) ruling in place, as operates in Northern Ireland without the world falling in.
As far as I can see, mother's maiden surnames are included in the birth records from 1900. I was able to find a couple of earlier birth examples, with maiden names, for my Driscoll family (see below), but none for either Santry or Kelly, so it seems a little haphazard.
Anyway, good to see them back.
(Thanks to Stuart McGee, who was up early this Easter Bank Holiday Monday!)
Wednesday 8 April (10:54am): Looks like the site is fully restored now and you can reach the Civil Records via the Home Page again.
Monday 20 April: Watch out for missing records! John Grenham has been investigating the revised collection in his Irish Times column.
