Brion

Brion is an English given name functioning as a variant spelling of Brian, which derives from an Old Celtic root, likely related to the element meaning high or noble, and possibly connected to the Old Celtic word for hill. The name was borne by Brian Boru, the famous High King of Ireland who died at the Battle of Clontarf in 1014, which helped cement the name's lasting popularity throughout the Irish diaspora and the English-speaking world. Closely related forms include Bryan, Brien, and the Irish Gaelic Briain.
