Irish citizenship & family history

Irish roots.
A wider horizon.

Ireland may be where the family story begins. Your future does not have to end at its borders. We research the connection and the evidence behind a possible Irish nationality route.

An EU nationality. A wider choice.

Irish citizenship is EU citizenship. The map highlights EU member states; longer residence remains subject to the applicable free-movement conditions.

The family connection

Start with the relationship.
Then check the timing.

Irish-born parentYou

A parent born in Ireland.

A person born abroad to an Irish-citizen parent who was born in Ireland is generally Irish from birth. The exact family facts and documents still need checking. source ↗

GrandparentFBR research

An Irish-born grandparent.

Birth abroad with a grandparent born on the island of Ireland can provide a Foreign Births Register route. Registration establishes citizenship under that route; ancestry alone is not the registration. source ↗

Parent registeredChild born

A parent registered before your birth.

For later foreign-born generations relying on Foreign Births Registration, a parent's registration before the child's birth can be decisive. A distant Irish ancestor is not an unlimited shortcut. source ↗

Think about the next generation

Timing is part
of the family story.

For families using the Foreign Births Register, registration before a future child's birth can affect that child's position. Research the sequence, not simply the surname. source ↗

Already have children? Their cases still deserve their own answers. Do not assume that a parent's later registration retroactively gives every child the same route.

The Jackson & Schwab approach

You bring the names.
We do the research.

Irish research is about more than identifying an Irish place name. We connect the relevant family relationships, check citizenship and registration timing, and organise the evidence around the actual route.

  1. 01

    Start with what you know.

    Names, approximate dates, places, family stories or existing records. Gaps are part of the work.

  2. 02

    Follow the evidence.

    We trace the relevant line and the events that could affect nationality. Evidence gaps stay visible.

  3. 03

    Get a written next step.

    A route assessment, the obstacles, missing proof and priorities for any further work.

Before you begin

Good questions.
Clear answers.

Is an Irish surname or DNA estimate enough?

No. The route rests on documented family relationships and the applicable nationality or registration rules, not a surname or an ethnicity estimate. source ↗

Can an Irish passport unlock the UK and the EU?

Irish citizenship combines EU rights with a separate ability to live and work in the UK under the Common Travel Area. Residence conditions and family rules still need checking. source ↗source ↗

Does an Irish citizen's non-Irish spouse automatically get UK rights?

No. A family member who is neither British nor Irish is not covered just because the Irish citizen benefits from the Common Travel Area. A separate immigration basis is needed. source ↗

What documents might matter?

Birth, marriage and relevant name-change records connect the generations. Where registration or naturalisation is part of the route, its certificate and date can also be important. source ↗

Do you guarantee Foreign Births Registration?

No. We research the route and evidence. Registration and passport decisions belong to the relevant authorities.
