For FBR Application (if eligible)

You must submit original civil documents for four generations: yourself, your parent, your grandparent, and your great-grandparent. Photocopies and church records are not accepted. The Irish government does not accept DNA test results from AncestryDNA, 23andMe, or similar services as proof of lineage.

• If your great-grandparent was born before 1864 (when Irish civil registration began), a baptismal certificate may be accepted
• If your parent acquired citizenship through naturalization or post-nuptial citizenship declaration, you must provide the original naturalization or post-nuptial certificate instead of an FBR certificate
