When you're in Kilkenny, this would apply to Waterford too, you will probably see lots of references to 'Ormond', like Ormond St/road, businesses & hotels with Ormond in the name. And you might just fleetingly wonder what that might refer to.
Ormond is the anglicization of the original Irish name of 'Urmhumhan' meaning 'East Munster'. Munster is the southerly irish province.
During the Norman invasions (1100-1200 +/-), Prince John of England granted the barony of Ormond to an English settler who was appointed Chief Butler of Ireland. Around the mid 1200's this family had adopted 'Butler' as their surname and ruled over Kilkenny and most of North & East Tipperary and became one of the most famous Anglo-Irish families in Ireland. The first Earl of Ormond was created in 1328 and they set up residence in Kilkenny Castle. However their power in Kilkenny was slowly eroded with the arrival of English settlers from the 1600's onwards.
