Ancient Irish Names & their History


All materials on this page are used with the kind permission of Pat Traynor.


Revised and adapted from "Irish Pedigrees" by John O'Hart, (Dublin 1892)
Volume 1, pg. 855. Volume 2, pg. 566.


As many of the ancient Irish surnames are not recorded in O'Clery's or in MacFirbis's Genealogies, or in the Linea Antiqua, or in the Betham Genealogical Collections, we have collected from "The Topographical Poems of O'Dugan and O'Heerin,""The Tribes and Customs of Hy-Fiachrach," and other works published by the Celtic and Archeological Societies in Ireland, the following Irish family names, and the modern anglicised forms which they assumed; (Hy-Fiachrach = descendants of Fiachra)

(1) "This is probably the family name now called MacHale". Dr.O'Donovan.

(2) O'Aodha; In Connaught since the Cromwellian Settlement of Ireland, the O' has been ommitted by most of the natives of that province. The Milesian gentry, there, however, still use that prefix as a mark of distinction between themselves and their co-relatives, the peasantry of the same race.

(3) O'Goirmghiallaigh; This Connaught family is distinct from the O'Gairmleadhaigh (or Gormley) family of Ulster.
