the Fragmentary Annals of Ireland. According to a Latin note prefixed to the manuscript, it was made for Rev. Dr. John Lynch, then Archdeacon of Tuam. It may also have been in 1643 that he transcribed Beatha Neimheadh Deidheanach (a legal tract) and the Chronicon Scotorum. Both of these may have been further copies made by Mac Fhirbhisigh at the behest of John Lynch. Seanchas Síl Ír At some point between 1643 and early 1645, Dubhaltach moved to the town of Galway, where in April 1645 he completed a transcription of the seventy-page historical-genealogical compilation called Seanchas Síl Ír. His source can be shown to be the late 14th-century manuscript called The Book of Uí Mhaine (also known as the Book of Ó Dubhagáin). Dubhaltach's very faithful transcript is especially valuable as four of the original fourteen folios have since been lost. Work for the Poor Clares On 8 December 1647, Dubhaltach noted that he had completed the translation – from English into Irish – of part of one book and all of a second concerning the Rule of St. Clare, and related matters. This translation was commissioned by Mother Mary Bonaventure Browne, Abbess of the Order of the Poor Clares in Galway. The initial section had been copied by Brother Mícheál Ó Cléirigh in 1636, and it was left to Mac Fhirbhisigh to complete it. He states in a note that his place of writing was the "College of Galway", most probably the college-house of the Collegiate Church of St. Nicholas, Galway. The college house was demolished in 1836, though the church itself is still in regular use. The Poor Clares are now based on Nun's Island in Galway city centre. Leabhar na nGenealach In April 1649, Mac Fhirbhisigh was working on what would come to be considered his magnum opus, Leabhar na nGenealach, or the Book of Genealogies. Nollaig Ó Muraíle describes it as "a compilation of Irish genealogical lore relating to the principal Gaelic and Anglo-Norman families of Ireland and covering the period from pre-Christian times to the mid-17th century and collected from a variety of sources." It is not known how long Dubhaltach spent collecting the necessary materials and planning the book's layout. Nor is it known when he commenced writing; he does note that on the "13 April, in Galway, 1649", he had completed a fifty-page tract on the genealogies of the Ui Bhruin down
