How Irish names are chosen

Irish names carry a political history that most naming systems do not. Ó, 'descendant of', and Mac, 'son of', hardened into hereditary surnames between roughly the tenth and thirteenth centuries, with the following word in the genitive case. From the fifteenth century English rule and later assimilation pressure stripped those prefixes off in large numbers. The Gaelic League, founded in 1893, drove them back on: families reattached the Ó and Mac their grandparents had dropped, which is why dual forms of the same person exist side by side — Pádraic Mac Piarais and Patrick Pearse are one man.

Irish spelling encodes consonant quality rather than English phonetics, so names look unpronounceable to English readers while being entirely regular in Irish.
