Brian
Meaning
traditionally "noble, high," its old Celtic root debated; the name of Brian Boru, the high king who broke Viking power in Ireland, which kept it beloved there for a millennium. A mid-century American everyman that still reads friendly and honest
The story
Brian reaches back to an old Celtic root scholars still debate, perhaps bri, hill or high ground, perhaps brig, might. What is not debated is the king. Brian Boru rose from a Munster kingdom to become High King of Ireland, and on Good Friday of 1014, at Clontarf outside Dublin, his army defeated an alliance of Leinster, Dublin, and Norse mercenaries. He was killed in his tent as the battle ended, victorious. Ireland has loved the name for the thousand years since, and his descendants, the O'Briens, still carry it as a surname. America discovered Brian in the twentieth century and would not let it go: the name climbed for six straight decades, peaked in the 1970s, then held near that peak for three more. Fitting, for a king remembered for never ceding ground.
