The contents also include a list headed 'The Names of some of the most Ancient Bards and Historians and the Time wherein [sic] they Flourished'. The lettering on the spine reads 'Llyfr Ieuan Lleyn, 1799' and the volume, except for the last five folios, appears to have been written between 1799 and 1822. The last four folios are partly in the hand of D. Silvan Evans and the folio immediately preceding them is probably earlier in date than 1799 and may belong to Cwrtmawr MS 513B, Part II.

A composite volume similar in format to Cwrtmawr MS 445 containing further transcripts by W. H. M[ounsey], 1861 (pp. 1-62, 65-80), copies (typewritten) of letters from Evan Evans to David Jones, Trefriw and to Richard Davies at Oxford and Holywell (pp. 81-127), a transcript of the poem 'The Love of our Country', 1772, and of a letter, 1767, from Evan Evans to Dr Humphrey Owen, Principal of Jesus College, Oxford, with a note (crossed out), 1868, from Evan Jones, Lampeter, followed by transcripts of other poems and letters included in the printed volume (1876). Loose in the volume are a transcript of a letter, 6 January 1777, from [David Jones] 'Dewi Fardd', Trefriw to Evan Evans and of a 'cywydd' by the same to the same (inserted after p. 127), and notes on Evan Evans in an earlier hand. J. H. Davies has written on the fly-leaves at the end of the volume: 'All printed in Gwaith I[euan] B[rydydd] Hir 1876 Except pp. 81-127'. The loose items were not printed either.

The volume is almost entirely in the autograph of Margaret Davies [Coetgae-du, Trawsfynydd]. The 'cywyddau' have been numbered, possibly at a date later than the time of writing, and it appears that several folios are wanting at the beginning. The initials 'P. W.' or 'P. Wm.' sometimes occur at the end of a 'cywydd' near the name of the poet.

A notebook containing 'englynion', 'cywyddau', etc. by (?) E. Anwyl, Ed. Moris, Rys Cain, Dafydd ab Gwilym, Dafydd Nanmor, Lewys Trefnant, Huw Machno, Edward Urien, Edm : Prys, Roger Cyffin, Huw Arwystl, Morys Berwyn, Ow.

At the reverse end is the beginning of a Welsh translation of A Practical Discourse concerning a future judgment by William Sherlock, D.D.

A[rmstrong] W[illiams], July 8 1886: 'Cannot find a name for this note book, so as to identify it on the Catalogue'. In the list of Cwrtmawr manuscripts it is described as 'Llyfr W. Rowlands, 1700'. J. H. Davies has added in pencil: 'W Rowland see R. Ellis article on Lhwyd' [i.e. Trans. Cymm., 1906-7, pp. 26-8].

A small volume, originally with clasps, containing 'cywyddau', 'englynion', etc. by Evan ab Evan (lines from Anacreon), Taliesin, Dafydd ap Edmwnt, John Philipp, Richard Philip, Dafydd ap Gwilim, Tudur Aled, John Dafies (Dafis), Owen Gwynedd, W(illiam) Llyn, Sion Brwnog (Brwynog), Dafydd Trefor, Dafydd Llwyd ap Llywelyn ap Gruffydd, Iolo Goch, Thomas Prys o Blas Iolyn Esgwier, Hugh Llwyd Cynfal, Doctor (Sion) Cent, Tudur Penllyn, Edward M[orus], Sr. Morgan, Rowland Vaughan, Hugh ap Ev. ap Ro[ ] and Wmphre David. The contents appear to have been transcribed after 1744 from a manuscript annotated by Lewis Morris, and a note on p. 100 suggests a connection with BM Additional MS 14866, although none of the poems are to be found in that volume. There are a number of quotations in the margins and elsewhere from Pope, Homer, Dryden, etc. At the beginning, in a later hand, are an 'englyn' by Siencyn Thomas Morgan and an 'englyn' which is described as being on the tombstone of the Reverend Alban Thomas of Blaen y Porth, Cardiganshire. A note in pencil on the limp boards which were originally inside the vellum cover reads 'Gwaith hen Feirdd MS from Rev. Armstrong Williams'.

A volume of poetry, chiefly in strict metre, written largely in the autograph of Owen Gruffydd (?1638-1730) between 1677 and 1692. Most of the poems are by Owen Gruffydd, but the following poets are also represented: Robin Ddu, Dafydd Gorllech, John Roger, Sion Phylip, Sypyn Cyfeiliog, Dafydd ap Gwilym, William Phylip, Gyttyn Owain ('medd rhai' 'Meredydd ap Rhys' in another hand), Ifan Tew Prydydd, Huw ab Iva[n], Bedo Brwynllysg, Edmwnt Prys, Edward Morys, Matthew Owen and Hugh Morys. There is a list of contents at the beginning and the poems have been correspondingly numbered. There are 'penillion' by William Elias on p. 309b. John Jones ('Myrddin Fardd') has supplied a lacuna in the manuscript from Peniarth MS 124. Almost all the 'cywyddau' in this manuscript, but not the 'englynion' and the poems in free metre, are to be found also in Peniarth MS 124, which is later in date than the present manuscript and written in a different hand. The pages have been numbered by Dr J. Gwenogvryn Evans and his report on the manuscript is in J. Gwenogvryn Evans MS 70a (under 'M[yrddin] F[ardd] 5'). If the information given on pp. 1 and 50 is correct, Owen Gruffydd was born in 1638. A note at the end (p. 238) of his elegy to Sir Roger Mostyn (d. 1690) states that the poet received fifty shillings for the 'cywydd'. There is a folio missing after p. 36 and another is wanting before p. 53.
