Irish manuscript now lost but cited by Mícheál Ó Cléirigh as a source for his transcription of the text Cogad Gáedel re Gallaib, of which he made a secondary copy in Brussels MS 2569-72 (dated March 1628 from Multyfarnham, Co. Westmeath). The title suggests an association with the bardic poet Cú Chonnacht Ó Dálaigh (d. 1139).
Manuscript used as an exemplar for texts in the Dublin, Royal Irish Academy, MS 23 P 12.
A manuscript now lost but apparently credited as a source for three poems in Brussels, Bibliothèque Royale de Belgique, MS 5100-5104, p. 53, in which Suibne is said to have composed the verse: Tuiccther asin rand sin ⁊ as an dá dhán gurab é Suibhne dorinne iad gé gurab ar Moling chuires as sein-leabhar iad .i. leabhur Murchaid meic Briain, “It is understood from this poem (rann) and from the two poems (dán) that Suibne composed them, although the old book, i.e. the book of Murchad mac Briain, attributes them to Moling”). The manuscript is apparently named for Murchad mac Bríain, i.e. son of Brían Bóruma.
