History & Origin

Brenan is a simplified spelling of Brennan, an Irish family name anglicized from Ó Braonáin, 'descendant of Braonán'. The root braon means 'a drop' or 'moisture', and the little personal name has sometimes been given the softer gloss 'little sorrow'.

As a first name it followed the broader fashion for Irish surnames on boys, though this single-N form always stayed rare next to standard Brennan. It reads as a contemporary surname-style name rather than a vintage one.

Did you know? Brenan is the leaner cousin of Brennan: it trickled into use in the nineteen-seventies and reached its small high point around 2009, still only a few dozen boys a year.
