Leabhar Adhamh Ó Cianáin
Leabhar Adhamh Ó Cianáin or The Book of Adhamh Ó Cianáin, now G 2-3 NLI (National Library of Ireland), is a book written in or about the 1340s by Adhamh Ó Cianáin by and for himself, and out of the book of his teacher, Seán Mór Ó Dubhagáin. Kenneth Nicholls has suggested that Adhamh wrote the book's genealogies between 1328 and 1350, which occur in the first half of the manuscript, which also contains the metrical Banshenchas.
