The remainder is in several hands of the late seventeenth or early eighteenth century.

A volume containing two collections of transcripts of poetry, with copious annotations, in the hand of Owen Williams ('Owain Gwyrfai'), Waunfawr.

Llwyd ab Dafydd ab Einion, Dafydd Pennant, Aneirin Gwawdrydd, Dafydd ab Gwilym, Lewis Môn, Rhys Goch Eryri', 'N.', Sion Cent, Sion Tudur, Gwilym ap Ieuan hen, Bedo Aerddren, Hugh Hughes ('Y Bardd Coch o Fôn'), Llywelyn ab Gutun, Gruffydd ab Ieuan ab Llywelyn Vychan, Syr Owain ab Gwilym ('Person Tal y llyn'), Hywel ab Dafydd ab Ifan, Thomas Prys o Blas Iolyn, Owen Gwyn[e]dd, Deio ab Ieuan Du, Tudur Penllyn, Iolo Goch, Llewelyn ab y Moel, Tudur Aled, Madog Benfras, Dafydd Nanmor, Sion Philip, Bedo Brwynllys, Lewis Menai, Gruffydd Grug, Syr Dafydd Trefor ('Person Llanallgo a Llaneugrad'), Dafydd ab Owain, Ieuan Tew brydydd, Dafydd Llwyd ysgolaig, Dafydd Llwyd [ap Llywelyn ap Gruffydd] and Hugh Arwystl; lists of titles and of first lines of poems by individual authors in the Lewis Morris MSS in the British Museum, taken from Y Greal, 1805-7, and from the scribe's own manuscripts; and lists of contents of 'Llyfr y Parch. O[wen] J[ones, 'Meudwy Mon'] Manchester', 'Llyfr Hir Bodadden', and 'Llyfr Byr Bodadden'. The sources used by the scribe for his transcripts of poems include 'L[l]yfr ysgrif Eiddo Mr. Owen Roberts gynt o Bentraeth Mon', 'L[l]yfrau Owen Gruffydd Llanystumdwy', and '[L]lyfrau M.S. pwdredig eiddo Mr. Jonathan Jones, Colector of Carnarfon 1855'. At the beginning is a list of poets whose titles were taken from Y Greal and a list of titles of poems transcribed in full. The collection was compiled during the period 1855-9, although the fly-leaf bears the scribe's name dated 1863. The second collection, beginning at the end, is entitled 'Y Gell Gynen, ('herwydd canau cynen sydd ynddo') and contains fliting poems ('ymrysongerddi') between Edmwnt Prys and William Cynwal and Sion Philip and Edmunt Prys, together with additional 'cywyddau' by Edmunt Prys. This section of the manuscript was compiled between 1844 and 1846, but there are some additions of the period 1859-61. Recorded on the upper end paper are timber purchase accounts of Owen Williams, 1844-5. The manuscript is lettered on the spine 'Owain Gwyrfai MS'.

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'.
