El apellido irlandés Maguire, McGuire, ó MacGuire ocupa el lugar nro. 29 en la lista de los más frecuentes en este país (ver lista). Dicha designación proviene de la palabra gaélica "MagUidhir". Este fue un clan que gobernó en Co.Fermanagh, en la provincia del Ulster, en las cercanías de Enniskillen. Aparece en los anales ya por el año 956, pero su preponderancia es del siglo XVI, permaneciendo durante los tres siglos siguientes en el Ulster. Aunque no fueron enteramente desposeídos, sufrieron importantes confiscaciones bajo Cromwell y Guillermo de Orange. Actualmente la mayoría de los MAGUIRE provienen de Fermanagh, y los MacGUIRE de Mayo y Roscommon. O'Hart dice que pertenecen a la línea de Heremon, descendientes de Cormac, hijo de Cairbre an Daimh Airgid, que es el Nº 91 en el pedigree de los O'Hart. En las listas de pasajeros llegados al puerto de Buenos Aires entre 1825 y 1880 se cuentan 17 personas de este apellido, que arribaron a nuestras playas entre 1835 y 1874.

The name is derived from the Irish Gaelic, Mag-Uidhir (Mag, Mac - son of & Uidhir - Dun colored, sallow). You can hear the actual pronunciation in Irish of the name at the PBS site Irish in America - Maguire. Uidhir is the possessive form of the proper name of Odhar & an interesting fact about that name is that it was in common use at the time of our progenitor because people are prone to name their children after hero's, Odhar being the name sake of a "hero-saint" who was St. Patrick's servant & chariot-driver, who reputedly saved his master's life by taking his place when his life was sought by pagans in about 452 A.D.
