Researching Mayo 1913-1923

Over the decade of centenaries there will be huge interest in researching the period. This section provides guidance to the most useful sources ranging from interviews with family relatives to researching in national institutions and online.

Our thanks to Dominic Price, historian and author of The Flame and the Candle, the seminal book on the period in Mayo, for his assistance in compiling the information below:

Researching the War of Independence and Civil War – Historical Sources for County Mayo


For the next decade Ireland will be commemorating the period which saw the country define itself as an independent nation. You may wish to know and learn more about the events which took place one hundred years ago when the 1916 Rising, the War of Independence and Civil War took place. The level of detail you wish to study will depend on you and exactly what you are looking for. The following areas will provide some guidance before you begin searching in archives. Historical research is fun but be patient. It takes a while to understand how each archive and its collections have been organised. Taking your time to explore will ensure you can best obtain what you are looking for.

Family and Relatives

Talking to members of the family is a good place to start. They have a lifetime of experience and will be able to fill in gaps with all sorts of interesting stories. Family members also have important details of the locations of former family homes and townlands, churches and graveyards. They will also know who you might ask for more information on a local level. Some families will also have old documents and historical artefacts which provide fascinating insights into family and general history of the period.

Historical Societies

Mayo is very lucky to have a number of excellent historical societies which have been undertaking quality historical studies for many years. Some of these studies are available in the various historical societies’ journals. Talking to these societies is well worth your while as they can advise you on what material might best suit your own study.

Libraries and Archives

Talking to an experienced librarian in National or County Libraries and in the various Archives is central to any progress. They will advise you on the best material for you to consult and will assist in using some of the computerised databases and microfilm viewers. They will also have met literally thousands of people engaged in research. They are very familiar with the archives in their care and therefore are one of the best ways for you to get results quickly.You can get afull list of irish public libraries at


The Internet can offer a lot of information on background reading and on archive collections which is free. It is also very useful for locating material or people you would like to research. There are also many useful images and maps which can be accessed easily. Simply type in the name of the person, event or place you are looking for and away you go. For more detailed research you will have to search the catalogues of the various libraries and archives.

National Archives now have excellent websites which are free to use. Some material can be viewed online whereas other collections will require a visit to the archive for consultation. The difficulty can be that there is a lot of material so you are not sure where to start. Identify the area you are particularly interested in and away you go!

Memorials and Ambush Sites

Memorials contain important details such as dates and names of people involved in historical events. Visiting an ambush site or town or village where certain events occurred is an important part of building up a picture of historical actions. Visiting such memorials can also be part of paying our respects to those who lost their lives. Lastly, a word of caution, many of the War of Independence memorials in County Mayo are situated on busy main roads. Extreme caution is advised in visiting such sites to ensure the safety of all concerned.

Historical Terms

When requesting information from archives it is important to use the correct language for historical references and terms. For example, the War of Independence referred to in Ireland is referred to as the Anglo-Irish War 1919-21 in the United Kingdom. Also the looking for RIC/British Intelligence Files on IRA or Cumann na mBan members may not yield any results because they have been filed under the heading ‘Sinn Féin Suspects’. One classic example was that of William O’Keefe Irish Volunteer Staff Officer from Claremorris. His Bureau of History Witness Statement on the War of Independence was filed under Manchester Active Service Unit. A good discussion with an archivist or reading the introductory material to collections on archive websites is a great way to begin more detailed research.  As you progress you will develop your own expertise around a certain field of study and the terms and references will flow. So do not be discouraged at the beginning keep working away and a lot of interesting material will emerge.
