Fictional Irish Genealogy is a sub-project of Fictional Genealogy. This project collects and identifies people for whom no historical evidence exists. Use this project for people who are the inventions of medieval Frankish chroniclers.


The core Irish tradition goes back to the Lebor Gabála Érenn (11th or 12th century), a collection of miscellany that takes the history of the Irish people back to Adam, and ties together all of the Irish royal lines into a common descent from folk hero Galamh / Milesius (Míl Espáine) whose descendants invaded Ireland and took it from the Tuatha Dé Danann (essentially the old gods).

The Lebor Gabála Érenn was supplemented and systematized in the 16th and 17th centuries by the Forus Feasa ar Erinn, Leabhar na nGenealach, and Annals of the Four Masters. These later works also assigned specific dates to the kings. Unfortunately, they assigned different dates.

The great 19th century Irish genealogist John O'Hart used Annals of the Four Masters as part of his book, Irish pedigrees; or, The origin and stem of the Irish nation (1892).

Unfortunately, this whole body of work is mythological.


  1. The About Me should specifically identify the original source.
  2. On Master Profiles, the curator note should include a summary. For example, Fictional character from the Lebor Gabála Érenn.
