Maps in Ireland are useful to conduct genealogical research. The island is smaller than most think at about 84,400 square kilometers (32,500 square miles). It is made up of 32 counties (including Northern Ireland), 12 cities, and more than 60,000 townlands, 2,500+ civil parishes and 300+ baronies.[1]
Traditionally, Ireland was divided into four provinces, and currently it is split into two jurisdictions, the Republic of Ireland and Northern Ireland. These regions divide into the counties and identifying your family's county of origin is key to finding your roots. After the county level comes parishes (both civil and religious) and townlands, even more granular.
Townlands of origin are helpful to locate land or tax-related records and you can correlate with parish maps to locate potential church records. Starting at the county level is often necessary before getting to a townland or parish of origin.

Historical ContextHistorical Context

Some of the earliest known inhabitants of Ireland were the Celts (specifically, Celtic-speaking groups known as the Gaels). They introduced the Gaelic language and brought with them a gradual diffusion of their culture and settlement with tribal settlements.
Before the Normans arrived in 1169, Ireland was divided into smaller tribes or dynasties and the map was divided into four provinces (Connacht, Leinster, Munster, and Ulster), four kingdoms, ruled by King Brendan of the Kingdom of Munster.[2]
One of the earliest maps or representations of Ireland was from Greek-Egyptian cartographer Claudius Ptolemy around 140 AD.[3] He depicted an island where it is located today. Some of the first printed maps of Ireland as a separate entity began around the 16th century.
