The principal concentrations of Hurleys are today found in counties Tipperary and Limerick, where they spread from the original Dalcassian homeland, and in Cork.
An interesting example of the pseudo-translation of surnames is found in Clare, where some whose name was originally Hurley have now become "Commane", since the Irish for the hurley-stick used in the sport of hurling is camán.
