Maps are helpful in locating the places where your ancestor lived. They help you identify neighboring towns, parishes, and geographic features. They can help you locate parish churches. They can show the transportation routes that your ancestor could have used in moving.
Maps may be published separately or in bound collections called atlases. Maps may also be found in gazetteers, guidebooks, local histories, directories, and history texts.
Different types of maps provide different types of information. Historical maps describe economic growth and development, boundary changes, migration and settlement patterns, military campaigns, transportation developments, effects of plagues, and other historical information. Road maps provide information on highways, rivers, and town sizes. Other types of maps include parish, county, topographical, enclosure, civil district, church diocesan, and many more highly specialized maps.
City and street maps are extremely useful when researching in the records of large cities. Locating an ancestor's address on a city or street map may help you determine which parish to search.
The major source of Irish topographical maps since 1800 is the Ordnance Survey, which covered all of England, Scotland, Wales, and Ireland. Maps were produced from the survey in series of 1 inch, 6 inches, and 25 inches to the mile. Series have been revised and published at different times. Ordnance Survey maps of greater detail (up to 10 feet to the mile) have been produced for most Irish cities. The following work explains the history of and details on the Ordnance Survey maps:
Harley, J. B. Ordnance Survey Maps: A Descriptive Manual. Southampton: Ordnance Survey, 1975. (Family History Library book 942 E3osa.)
Maps must be used carefully because:
- Several places often share the same name. For example, more than seventy localities in Ireland are named Kilmore.
- The place-name on the map may not be spelled as expected.
- Parish boundaries are seldom indicated, so you cannot assume that a locality lies within a certain parish unless the map specifically shows that it does.
Finding the Specific Place on the Map
To be most effective in researching your Irish ancestor, you must identify the place in Ireland where your ancestor lived. Search gazetteers, histories, family records, and other sources to learn all you can about the place where your ancestor lived, including:
- The parish and county the place was in.
- The civil district your ancestor's parish was in (if your ancestor lived in the place after 1864).
- The name of the church where your ancestor was baptized or married.
- The names of other townlands in the parish.
- The names of nearby places, especially large cities.
- The names of places where related ancestors lived.
- Nearby geographical features, such as rivers and mountains.
This information will help you distinguish the place you are searching from other places of the same name.
See the "Gazetteers" section of this outline for additional information on locating places.
Finding Maps and Atlases
Collections of maps and atlases are available at numerous historical societies, county record offices, and public and university libraries. Major map collections in Ireland are housed at the Ordinance Survey Office.
