Description

Descending directly from the legendary High King Brian Boru, the O’Brien clan ruled the ancient kingdom of Thomond with fierce brilliance for generations, consistently shaping the political destiny of the island. In Historical Memoir of the O’Briens: The Origin and History of the O’Brien Clan, distinguished scholar John O’Donoghue constructs an authoritative, monumental investigation into this historic family line.

First published in the 19th century and recognized as an elite genealogical classic, this volume traces the clan’s path through centuries of turbulent history—from the glorious victory at the Battle of Clontarf, through complex shifting alliances with Anglo-Norman lords, to their transition into the Earls of Thomond under the Tudor monarchy. Drawing directly from ancient Gaelic annals, state papers, and royal patents, O’Donoghue builds a flawless, highly accurate reference that serves as an indispensable asset for genealogists, researchers, and proud members of the O’Brien family worldwide.
