Along the storm-battered cliffs of Beara, the Sullivans’ courage and ambition first took shape. From castles towering over the Atlantic, they safeguarded their lands and people, and from those heights, they must have felt the pull of the horizon, imagining new worlds yet to be conquered. Descending from Eoghan Mór, the Sullivans claimed kinship with the greatest families of Munster. Their name, "dark or hawk-eyed," reflected their reputation for defense, easily spotting danger from their cliff-top towers. Sullivan Beare and Sullivan Mór commanded lands where even seasoned English armies feared to tread, maintaining Gaelic law and custom long after others had bent the knee. When Donal Cam O'Sullivan Beare led his epic winter march, 300 miles from Beara to Ulster, the family became the stuff of ballads and legend. Though they eventually lost their empires to the English, the Sullivans never lost their defiance. The Great Famine emptied Sullivan territories, sending thousands to Boston, New York, and beyond aboard ships departing from Cobh and Bantry Bay. There, the Sullivans faced new kinds of battles. John L. Sullivan became boxing's first superstar, the "Boston Strong Boy," who fought with bare knuckles and Irish pride. Ed Sullivan brought entertainment to millions on Sunday nights. And Louis Sullivan, the father of the skyscraper, gave form to American ambition. Sean Kelly’s latest volume in the Irish Genealogy Series reflects a lifetime dedicated to preserving Ireland’s clan histories. Through archives, ship records, and family letters, he traces the Sullivan journey from warriors on the cliffs to architects of a new world. For Sullivan descendants worldwide, this book is more than history. It is a celebration of courage, vision, and an unbroken Irish spirit. Your heritage awaits.
