You could try the index on FamilySearch which goes to 1958, mother maiden name is hit and miss though.

Catholic civil records don't start until 1864 or 1865, someone else will remember which year exactly. Protestant marriages start about 1854 if I remember right. Births and deaths in 1864 or 5.

Births, Catholic marriages and deaths - 1864
Protestant and Registrar's Office marriages - 1845

Thank you, I'm going to file this somewhere for future reference.

Death missing (1879) even though there are are probate and will register entries.
Northern Ireland: apparent birth entry spelling error in forename (1897).
It is at variance with two censuses and death.

It was known to the GRO that some deaths were not registered. People were buried a day or two after death and some didn't then go the GRO. One of the early Register General Reports comments that there were more burials in Dublin cemeteries than there were registrations. It improved but even in the 1910-20's there is the occasional one I have been unable to find despite paging through the district images the newspaper stated the death was in.

Both IrishGen and GRONI have transcriptions errors just as Ancestry and Findmypast do. Both have a report an error facility.
GRONI do not index the same images as IrishGen. GRONI index and provide images of the original bound register books. IrishGen index and provide images of the loose leaf quarterly copies sent to Dublin. There are some period copy errors made be the clerks that escaped QC just as in England: Local BMD or GRO BMD.

The spelling of a forname in an index should accurately reflect the entry, which may be at variance with censuses and death, they were written by different people and info was given to the GRO clerks verbally then the informant asked to check, sign or make their mark, the quarterly return image would be on irishgen.

It is possible to report indexing errors in the database, but copying mistakes or omissions happened much earlier, as you say, between local registrar and the central office, so Bugbear can expect some hiccups.  I cannot believe a substantial and lengthy will (over £10,000 with scores of beneficiaries) gained probate without a death certificate.  The entry just probably never reached Dublin.  Anyway, I have told them about it.

Agree. Strange things happened. Example in my tree for a much less amount and just an Admin, but granted without a death cert/registration.

Death Registration 11 months later: 21 Oct 1930 with an clerical error such that it was apparently registered before death:
Death 6 Nov 1930 at Billis of Joseph Henry Wetherall, aged 63, Married (School Teacher). Registered 21 Oct 1930 by M Wetherall, present at death, of Billis.

Northern Ireland: apparent birth entry spelling error in forename (1897). It is at variance with two censuses and death.

In Northern Ireland it's not uncommon for variation of spellings in names (both Christian and surnames) up until probably WWII. Also some Christian names here are interchangeable- here are just a few but there are many more-
Agnes, Ann, Anne, Nancy, Hannah
Bridget, Delia
Peter, Patrick
Jane, Jean, Jeannie, Jessie
Ellen, Helen, Nellie
Jeremiah, Darby

The birth registration I had was Calice, the censuses and death gave Canice, neither of which I had seen before.  I found Canice is the name of an Irish saint, and a version of Kenneth. The family was RC, so it made sense.  They were literate, both parents at marriage were compositors, mother filled in the 1911 census because father was absent, so I decided they both probably knew how to spell their son's name.  (Perhaps the registrar's clerk was protestant.)

Looks like a simple spelling error by registrar-

That was my conclusion.  I thought you might find it!

The mother was married as Frances, at one birth she gave Frances Emily, in 1901 she was Emily, then back to Frances in 1911 - "married 24 years",  -  so all the same person.
