This includes obtaining a long-form birth certificate from the General Register Office in Ireland. you must show that your parent was an Irish citizen at the time of your birth. If your parent was born outside of Ireland but was an Irish citizen, you may still be eligible.

When claiming through a grandparent, you must demonstrate that your parent was born outside of Ireland and that they did not acquire Irish citizenship before your birth. If your parent was not born in Ireland and did not register their birth in the Foreign Births Register, you may not be eligible for citizenship.
