descendant of Brian
Type
Patronymic
Root
Irish Ó Briain
Chiefly
Clare, Limerick and Tipperary

From Brian, a personal name usually connected to a root meaning ‘noble’ or ‘high’. The Ó prefix was widely dropped under English administration and widely restored in the nineteenth and twentieth centuries.

Whether a family writes O’Brien or Brien today is often a matter of when an ancestor filled in a form.

An honorific Lord or Lady certificate in the O’Brien name, hand-finished and sealed, with a square metre of Scottish woodland dedicated alongside it. A novelty, magnificently done — and a good deal more fun than a family tree.
