History of the O'Halloran name
Ó hAllmhuráin derives from allmhurach, a 'stranger from over the sea', suggesting an ancestor famed as a raider or seafarer. Two septs bore the name: one of the Dál gCais in east Clare near the Shannon, and another, Clann Fhearghaile, whose chiefs held territory just west of Galway city until the Norman-founded town displaced them. The name remains firmly rooted in Clare and Galway. Its most illustrious bearer, the Limerick surgeon Sylvester O'Halloran, pioneered eye and head surgery in the eighteenth century, wrote passionate histories of Gaelic Ireland, and helped inspire the foundation of the Royal College of Surgeons in Ireland.
