Brian

Brian is an English and Irish given name derived from the Old Irish name Brían, whose root is generally interpreted as meaning "high" or "noble," possibly from a Celtic element related to the Proto-Celtic word for hill or elevation. The name was borne most famously by Brian Boru, the High King of Ireland who defeated the Vikings at the Battle of Clontarf in 1014, cementing the name's enduring prestige in Irish culture. Its popularity spread throughout Britain, particularly through Breton settlers who arrived after the Norman Conquest. Related forms include Bryan, the Breton variant Brieuc, and the Welsh name Bryn.
