A volume containing forty-three odes composed and written by Wiliam Kynwal between 1567 and 1576 (ff. vii verso, 1-93). He began the manuscript at Cerrig Ellgwm 'yn fy siambr vy hun yngheric Ellgwm y trydydd dydd o vis mai o vewn yssbyty dol gynwal a duw a wyr na wnn pwy na[c] ym ha le y gorffennir ef' (ff. v verso-vi). The odes are headed by the arms of the persons addressed, except in the case of the odlau merched, in which quaint sketches of women are substituted.
Also included are a prologue (ff. 5-6) and an incomplete table of contents (f. 6 recto-verso). At the end of the manuscript there is a rough copy of an ode by Huw Machno (ff. 95-96), who has also written some notes on the folios at the beginning (ff. i-iv).

Notes in the hand of Chancellor Wynne, comprising notes on Anglesey and on Welsh genealogies (pp. 1-8); a genealogical table of the pedigree of Edward Wynn of Bodewryd (pp. 9-15); abstracts of deeds relating to Bodewryd and Tyndryvol, and copies of papers relating to lawsuits (pp. 17-90); some memoirs relating to Chwaen wen and Bodowir (pp. 91-98); and biographical notes of some members of the Bodewryd family (pp. 99, 107-110).
Also included is a copy, in the hand of Hugh Hughes, of a cywydd, 'Marwnad Dd. ap Rhees ap Lle'n ap Gr. Tad Hugh Gwynn Bodewryd a Phirse Llwyd Gwredog' by Sion B[rwynog] (pp. 15-16).

A volume of Welsh poetry mostly in the hand of Humphrey Davies (Wmffre Dafis), [vicar of Darowen], contining copies of cywyddau and awdlau by well-known and less known poets from the early fourteenth century to the early seventeenth century (pp. 25-492). Some poets are well represented, especially Ieuan Tew, Sion Keri and Huw Arwystl.
Twelve folios at the beginning (pp. 1-24), as well as six (formerly loose) folios at the end (pp. 493-504) are in the hand of Evan Lloyd of Blayn glyn, a former owner of the volume. These include a copy of a version of the dialogue between Hadrian and Epictetus, beginning: 'llyma ymddiddanion Rhwng adram [sic] emerodr Rhufein ag Epig y ddav wr calla yn y bvd', which differs greatly from the text found in Llyfr Yr Angkr and the Hengwrt MSS (pp. 3-7). Two other leaves (now bound in at the end of the volume), one bearing a Welsh poem in free metre (pp. 505-506) and the other an assessment of Derwen parish, [Denbighshire] (pp. 507-508), do not seem to belong to this volume.

A composite volume, the first portion of which (pp. 1-78, old foliation 1-38), written in the early eighteenth century, contains selections from Flores poetarum, triads, englynion, the divisions of Wales (pp. 29-33), cywyddau, poems in free metre, and an incomplete table of the contents of the latter portion of the volume (pp. 57-59). The second part of the volume (pp. 79-406, old foliation 1-245 with gaps) has been neatly written in two or more hands, one of the seventeenth century and the others of the early eighteenth century. It contains Welsh poems in strict and free metres from the fifteenth to the eighteenth centuries, many of them either of Anglesey interest or written by Anglesey poets, particularly Lewis Môn, Sion Brwynog and John Griffith of Llanddyfnan.
Among miscellaneous items are copies of the Articles of Agreement between the Parliamentary Commissioners and the inhabitants of Anglesey, 1648 (pp. 295-296); Sir Edward Trevor's riddle (p. 312); and a short bardic grammar (pp. 358-362).

A volume of genealogies of Anglesey families, mostly of the maternal descent. Also included are a cywydd by Ie[u]an Tew Brydydd, 'Kowydd i ofyn cyngor i'r llwynog' by Hugh Lloid (Cynfel) (pp. 156-157) and a poem in free metre, written in 1636.
Five fragments of parchment have been pasted in on pp. 171, 173, 175, 177 and 179.
