Brennan is the anglicised form of the Gaelic Ó Braonáin, "descendant of Braonán," a personal name built on the Old Irish word braon, a drop — read in the older poetry as a drop of rain, or of sorrow, and carrying a sense of liveliness. What sets Brennan apart from many Irish surnames is that it was never a single family: at least two separate septs adopted the name independently, so a Brennan from one county may share nothing but the surname with a Brennan from another. The best documented branch held land in Counties Kilkenny and Carlow in southeast Leinster, operating within the political world of the MacMurrough Kavanagh kings who dominated the province after the Norman invasion. A second, unrelated Brennan sept was rooted in County Roscommon, in the Connacht borderlands governed by the O'Connor kings.
Both lines endured the same disruptions that reshaped Gaelic Ireland — the Tudor conquest and, later, the Cromwellian land settlements of the 1650s — yet the Brennan name held on in Kilkenny, Carlow, and Roscommon through the centuries that followed, and the Great Famine sent later generations to Britain, the United States, Australia, and Canada. The name went on to distinguish itself well beyond Ireland: Walter Brennan won three Academy Awards, a record for any supporting actor; William J. Brennan Jr. served thirty-four years on the U.S. Supreme Court; and Dublin-born Maeve Brennan became one of the finest prose stylists to write for The New Yorker.
This collection gathers that heritage into everyday pieces — crest blankets, flags, ornaments, drinkware, and apparel set against the Irish national tartan — for Brennan families marking either branch of their history. The fuller story of both septs is told in our history of the Brennan Irish surname.
