OBrien Genealogy & Family TreeO’Brien is an Irish name from Thomond, Ireland, where the oldest known O’Brien ancestor—Brian Boru, King of Ireland—was recorded in the 10th Century. The name means “descendant of Brian,” named after the same king, who drove the Norseman out of Ireland in the Battle of Clontarf. Roots for this name can also be found in Germany and Spain. The family motto is Lamh laidir an Uachtar which means “The strong hand from above.”

One of the first O’Briens to come to America was Andrew O’Brien in Pennsylvania in the 1840s.
