Leabhar na nGenealach

Leabhar na nGenealach ("Book of Genealogies") is a massive genealogical collection written mainly in the years 1649 to 1650, at the college-house of St. Nicholas' Collegiate Church, Galway, by Dubhaltach MacFhirbhisigh. He continued to add material until at least 1666, five years before he was murdered in 1671. The original 17th century manuscript was bequeathed to University College Dublin (UCD), by Dublin solicitor Arthur Cox in 1929, and can be consulted in UCD Library Special Collections. The manuscript can be viewed online at Irish Script on Screen, which is available in English, and in Irish. Leabhar na nGenealach, was reprinted, and published in a five volume edition in Dublin in 2004 as The Great Book of Irish Genealogies.
