90 Day Ruling and Travelling on a UK Passport

Grandparents are the furthest back you can go . Not great grandparents.

I agree, having been through this. Although my great grandfather his wife and daughters were Irish, by an unfortunate scenario, my grandfather was born in England, during an Army deployment, so my application was unsuccessful, confirming it only goes as far as grandparents, and must have been born in Ireland. (According to the Irish Government).

Sorry, you are wrong, I just assisted someone in getting an Irish Passport from Great Grandparents (a great Grandmother) born in Northern Ireland in 1933. The Irish Government ruling was changed recently 

When did you apply as the ruling has now changed 

In theses circumstances…

If your grandparent had Irish nationality, or if your great-grandparent was born in Ireland and your parent registered with the Foreign Births Register before you were born, you will still qualify for Irish citizenship.

Can you qualify for citizenship through your great-grandfather?

Yes, you definitely can! The thing is, Ireland, a nation with a population of just under 5 million, has issued over 4 million official passports currently circulating worldwide. This extraordinary number of passports can be attributed, in part, to the enduring doctrine of jus sanguinis, or citizenship by descent, which forms the bedrock of Irish nationality law. This principle grants individuals the right to claim Irish citizenship based on their ancestral bloodlines, even if they have never set foot in the country. Embracing this inclusive perspective, Ireland extends its citizenship beyond territorial borders, enabling millions of people globally, including majority of the 40 million U.S. citizens with Irish ancestry, to become holders of Irish passports.

This table from the Irish Citizens Advice page explains the process. Your birth must be on the Foreign birth register if using a grandparent, costs €278 currently. If you are using great grandparents your parent birth must have be on the FBR before you were born.

If you are:

Then you are:

A

Born in the island of Ireland on or before 31 December 2004

Entitled to Irish citizenship or you are an Irish citizen

B

Born on the island of Ireland on or after 1 January 2005

Entitled to Irish citizenship if one or both of your parents:

Is Irish Is British or entitled to live in Northern Ireland or the Irish State without restriction on their residency Is a foreign national legally resident in the island of Ireland for 3 out of 4 years immediately prior to your birth

C

Child of A, born outside the island of Ireland

An Irish citizen

D

Child of C and a grandchild of A, born outside the island of Ireland

Entitled to Irish citizenship, but you must first register in the Foreign Births Register

E

a child of D and a great-grandchild of A, born outside the island of Ireland

Entitled to Irish citizenship, by having your birth registered in the Foreign Births Register, but only if your parent D had registered by the time of your birth.

Thanks to those who highlighted routes towards Irish citizenship by descent, and thus hopefully qualifying for an Irish passport in addition to their UK passport.

I checked my documentation regarding the rejection and find any flexible exceptional discretion by the Minister was unsuccessful, the great grandparent logical qualification seemed to fail as no descendant since then had been born in, or could demonstrate residence in Ireland, including me. I could not start this application again, so must exit the subject, but by all means carry on with this useful discourse, especially posting any recorded success, with evidence, as I am sure many would like to travel the route to dual citizenship. My motive was to find a method of being acknowledged as still an EU resident after Brexit.
