Murphy
Meaning
surname Ó Murchadha, "sea warrior"
The story
Murphy is the most common surname in all of Ireland, from the Gaelic Ó Murchadha, meaning descendant of Murchadh, a name that itself joins muir, the sea, with cath, battle, so it reads as sea warrior. It carries the whole warmth and grit of Ireland in three syllables. As a first name it has a bright, friendly, slightly mischievous air, helped along by film and television and by the affection people feel for the surname. It works easily for a girl or a boy. Brand new in that role, Murphy has climbed fast in the United States and reads as current as it has ever been, part of a love of Irish surnames worn up front. Cheerful, sturdy and unmistakably Celtic, Murphy hands a child a sea warrior's old courage wrapped in one of the friendliest sounds Ireland ever made.
