"The Northern Ireland Place-Name Project, established in 1987, researches the origin and meaning of the place-names of Northern Ireland. It is the only centre for the study of Gaelic place-names in the United Kingdom, with parallels in the Institute for Name-Studies in the University of Nottingham in England, and the Archif Melville Richards Place-Name Database in the University of Bangor, North Wales. The Northern Ireland Place-Name Project grew out of the work of the voluntary Ulster Place-Name Society established in 1952, and supports the aim of the Scottish Place-Name Society to achieve a similar centre for the study of place-names in Scotland. Within Ireland, the Northern Ireland Place-Name Project co-operates with colleagues in Dublin in the Placenames Branch of the Department of Community, Rural and Gaeltacht Affairs, and in the Locus project on historical Irish place-names in University College Cork.
The place-names of Northern Ireland include those of 6 counties, 60-plus barony and district names, 269 parishes, 9,600 townlands and at least 20,000 other names, in the languages of Irish Gaelic, English and Scots, with a few names in Latin or Old Norse. The gazetteer compiled by the Northern Ireland Place-Name Project is still growing, with current additions including both traditional names of fields and modern streets. There has always been a strong "community relations" aspect to the work, since everyone lives in a place."
The townland can also be located on a map and when you zoom into the map you're also given the option of historic maps from 1830 and 1850. I've noted a problem with the former. It would appear that there is an overlay from another location on the townland I chose to view.
