Can I Get an Irish Passport If My Great-Grandparents Were Irish?
Not directly — Irish citizenship does not automatically extend to great-grandparents. But depending on your family, there is one narrow pathway where it can still work.
1. Standard Rule
You cannot claim Irish citizenship solely because a great-grandparent was Irish.
Ireland only automatically allows descent through:
Irish-born parents
Irish-born grandparents
2. The Exception: The FBR Chain
You can qualify if your parent:
Registered in the Foreign Births Register,
And did so before your birth.
This maintains the legal chain:
Great-grandparent → grandparent → parent (registered) → you.
3. When This Works
The loophole applies if:
Your great-grandparent was born in Ireland
Your grandparent was not registered
Your parent did register early
You were born after the registration
4. When It Doesn’t Work
You cannot qualify if:
Your parent registered after your birth
No one in the middle generation registered
You try to skip the chain
Ireland does not permit retroactive transmission.
5. What You Can Still Do
If you aren’t eligible:
Your parent may still register (you won’t qualify, but your children might)
You can become Irish through residency (5-year rule)
Bottom Line
Great-grandparents alone do not entitle you to an Irish passport — unless your parent registered before your birth.
