The study of placenames has a long tradition in Ireland. Classics of the field include Joyce’s The Origin and History of Irish Names of Places, among others. The standout modern day effort is the work of the Placenames Database of Ireland.
More localized and specific examples abound and one such publication is the work of William Shawn Mason. In volume two of A Statistical Account or Parochial Survey or Ireland he gives the following origins for the townlands in the civil parish of Kilmacahill.
