Halloran

Halloran is an Irish surname with deep historical roots, originating from the Gaelic Ó hAllmhuráin. The name means "descendant of Allmhurán," where the personal name Allmhurán is derived from allmhurach, meaning "foreigner" or "stranger from across the sea." This etymology reflects the influence of Norse or other external settlers in early medieval Ireland, who were often characterized as outsiders. The name is primarily found in the western regions of Ireland, particularly County Galway and County Clare.
