How to label suburbs and townlands (Ireland)

From Wazeopedia

There are very few name clashes in Ireland for town of over 800 inhabitants. Use the common name without a county appendage - otherwise the map looks very cluttered. Sometimes it is necessary to append a county e.g. to distinguish between Newport Mayo and Newport Tipperary. Only add the county if absolutely necessary. In Dublin city the name Dublin is not very useful so please use the suburb names as they appear in the 1:15000 Ordnance Survey maps (available in petrol stations and many shops). Don't append - Dublin, (Dublin) or other qualifier as this makes the map very unwieldy.
