The most frequent family names with roots in County Cork — names that spread through Ireland and the Irish diaspora:
Cork is Ireland's largest county and its people will tell you — with some conviction — that it should be the capital instead of Dublin. The 'Rebel County' earned its name in the fifteenth century when it backed the Yorkist pretender Perkin Warbeck; it earned it again in the War of Independence, when Cork city produced Michael Collins, Tom Barry, and an extraordinary generation of republican fighters.
Murphy is the most common surname in Ireland, and Cork is its heartland. The name derives from Ó Murchadha — "sea warrior" — and the Murphys of Cork were a sept of the MacCarthys, the ancient Munster kings. O'Sullivan, the second-most common Irish surname, also has its roots primarily in Cork and Kerry.
Cobh (pronounced 'Cove', formerly Queenstown) is Cork Harbour's port town — and one of the most significant places in Irish-American history. It was the last port of call for the Titanic. More importantly, it was the departure point for almost three million Irish emigrants between the Famine and the Second World War. If your family left Ireland, the odds are significant that they left from Cobh.
The Murphy diaspora in America is enormous — it's among the top ten most common surnames in the United States. Cork families built communities in Boston, New York, Chicago, and San Francisco. The Fenian movement, which sought Irish independence from American shores, was disproportionately Cork-born in its leadership.
