It is being made available for download in XML format under the Open Database License (ODbL) v1.0 by Gaois, Fiontar & Scoil na Gaeilge, DCU and the National Folklore Collection, UCD. Please note that this is not an authoritative index of surnames, nor has it been edited. Feedback is welcome at firstname.lastname@example.org.
