School records, including alumni lists, may contain valuable information about your ancestor, including name, birthplace, residence, and father's name and occupation.
The main Irish college, Trinity College in Dublin, is a Protestant college but was attended by some Catholics. Brief biographies of Trinity College alumni appear in:
Burtchaell, George Dames, and Thomas Ulick Sadleir, eds. Alumni Dublinenses 1593-1843. London, England: Williams and Norgate, 1924. (FHL book 941.83/D1 J2u; film 990,388 item 2.)
Most school records remain in local custody, though a small collection of school records for the Republic of Ireland is held at the National Archives.
Northern Ireland school records and their Family History Library call numbers (when applicable) are listed in the following:

If your ancestor received professional training, he or she may have attended school in another country. Many Irish professionals were trained in other countries. For example, Anglican ministers were often trained in England, doctors in Scotland, and Catholic priests in France and Italy. Therefore, if you cannot find Irish school records for your professionally trained ancestor, you may want to check school records of other countries.
