Ireland and it's counties are sub-divided in a unique way. The smallest and most significant division is what is known as the "Townland"
Counties are divided into Parishes and Parishes further divided into townlands.
This ancient method of land measurement is found only in Ireland and is very important in genealogical research. These small areas of land can vary in size from a few acres upwards and are the basis of the most important of all Irish Genealogical Records , Sir Richard Griffith's Valuation of 1848-1865. There are approximately 62,000 townlands in Ireland and anything from perhaps five to thirty townlands can be grouped together to form a Parish.
