Briannan is of Irish origin, derived from the ancient Celtic word 'Brian,' which means 'strong' or 'noble.' It's a variant spelling of Brian, but with a unique twist that sets it apart. Briannan gained prominence in Ireland during the Middle Ages and was borne by several notable figures throughout history.
Briannan was quite popular in 1989 and 1993 with five births each year, totaling ten children given the name over those two years.
