A volume in the hand of D. Silvan Evans containing 'awdlau' and 'cywyddau' by Wiliam Lleyn. The transcripts were made c. 1869 and appear to be taken from more than one source, e.g. a manuscript of Paul Panton, 1779, and a manuscript of W. H. Mounsey based on a manuscript in the hand of [Owen Jones] 'Owen Myfyr'. At the end are 'Tri o'r Chwe Englyn a ddywedir i Ddafydd ab Gwilym wneuthur ar ei Glaf-wely' transcribed by D. Silvan Evans from a manuscript in the hand of ?D[avid] Ellis [Cricieth]. Beginning at the end are three pages of notes on 'Matter'.

An imperfect composite volume written in a number of hands but mainly in a late sixteenth century hand. The following note by J. H. Davies is written on one of the upper fly-leaves: 'This MS is supposed to be in the hand of Sion Brwynog (see Cwrtmawr MS 11.493). It was copied by the Rev. David Ellis, then of Amlwch in 1777 and was then perfect. The copy is now MS 11 in my collection'. This supposition cannot be correct since Siôn Brwynog died in 1562 and some of the poems were composed after that date. The hand also differs from that in Peniarth MS 61 which J. Gwenogvryn Evans tentatively attributed to Siôn Brwynog (See also Eurys I. Rowlands 'Llaw dybiedig Siôn Brwynog', Cylchgrawn Llyfrgell Genedlaethol Cymru (The National Library of Wales Journal), Vol. VII, pp. 381-2). The volume contains 'cywyddau' and a few 'awdlau' by Mathew Bromffild, Tudur Aled, Jhon Brwynog, Lewys Mon, Jhon Tudur, Rys Goch Glynn Dyfrdwy, Morys ap Ieuan ap Einion [Morus Dwyfech], Gwilym ap Sefnyn, Gvttor Glynn, Howel Reinalld, Wiliam Llyn, Lewis Daron, Dafydd Pennant, Roger Kyffin, Gwilym ap Ifan Hen, Gvttvn Owain, Cynwig ap Dafydd Goch, Owain ap Ll[ewelyn ap y] Moel, Rys Goch yr Yri (Rys goch ap D'd), Robin Ddv Fardd, Tudur Penllyn, Rys Pennarth, Lewys ap Edwart, Lewys Daron, Lewys Menai, Robert Ifans, Lewys Morgannwg, Owain Waed Ta, Gruff. Gryg, Iolo Goch, Grvffydd Llwyd ap D'd ap Einion and Hvw Pennant; English verses by J[o]hn Powell and Hu: Powell; etc. There are marginal and other annotations by William Maurice, Cefn-y-braich, ?William Wynn, Llangynhafal and David Ellis, Cricieth, and a transcript by the latter of the greater part of the volume forms Part II of Cwrtmawr MS 11. Some of the pages which have been repaired have also been made up by a later hand and the ink in these portions has faded badly. One page of the volume has been made up by J. H. Davies. The spine is lettered 'Llyfr Kywyddau'.

A composite volume containing a list in the hand of the Reverend Robert Williams, Rhydycroesau of titles and opening couplets of 'cywyddau', 'awdlau', etc. by Rhys Goch Eryri, Robin ddu ('o Hiraddug'), Sion Tudur, Dafydd Llwyd ap Llewelyn ap Gruffydd ('o Fathafarn'), Sion Prys (Caerddinen), Iolo Goch, Dafydd ab Gwilym, Tudyr Aled, Edwart Ralph, Guto'r Glyn, Dafydd Gorloch [sic], Robert Clidro, Syr Thomas Chwith, Owain Gwynedd, Edmund Prys, Dr Sion Cent, Meredydd ap Rhys, Lewis Glyn Cothi, William Cynwal, Sion Brwynog, Llawdden, Dafydd ab Edmund, Dafydd Nanmor, William Lleyn, Simwnt Fychan, Thomas Prys (Plasiolyn), Rees Ednyfed, Thomas Evans, Huw Arwystli, Llewelyn ap Owain ap Cynrig, Gruffydd ap Efan ap Llewelyn Fychan, Llewelyn Amredydd ab Ednyfed, Edward ap Rhys, Robert Dafydd Llwyd (Aber gwyn gregin), Owain Gruffydd (Llanystumdwy), Watkin Clywedog and [John Davies] ('Sion Dafydd Las'); transcripts by Howel Lloyd, with copious annotations, of two 'cywyddau' by Iolo Goch; transcripts (paper water-marked 1827) of 'cywyddau' by Doctor Sion Kemp, Sion Phylip, Evan llwyd brydydd, Wiliam llyn, Sion tudur, Robart ap Rys wynn ('o raeanog'), Iolo goch, Tudur penllyn, Gutto'r glynn, Huw ap Dafydd, Gruffudd hiraethog, Ifan ap tudur penllyn, Howel Reinallt, Rys goch oryri, Tudur Aled, Ierwerth fynglwyd, Dafydd llwyd ap ll'n ap gruffudd, Robin ddu ap siankin, Gwilym ap sefnyn, Lewis mon, Lewis Daron and Dafydd ap gwilim, and a Cornish vocabulary (from BM Cotton Vesp, MS A.

The majority of the prose texts were transcribed from manuscripts in the British Museum during the period 1859-60 and many of them were printed in Y Brython, 1859-60. The spine is lettered 'Welsh and Irish Tracts. W. H. Mounsey'.

A volume (watermark 1870) containing transcripts of poems in strict metre by Gruffydd Phylip, Syr Owain ap Gwilym, Richard Phylip, Siôn Phylip, Siôn Dafydd Siancyn and Richard Cynwal. The original pagination is defective and sections are wanting at the beginning and elsewhere in the volume. The volume was probably transcribed by Robert Prys Morris ('Robyn Frych'). The name 'Robyn Frych?' has been written in pencil inside the front cover.

A volume (78 pp.) written in several hands, in part at least between 1755 and 1763, containing medical recipes headed 'Cynghorion', 'englynion' by William Phylip, Gr. ap Ievan 'o lannerch llyweni', 'Robin ddu o hir Addig', Einion ap Gwalchmai, extracts from 'Talysau [sic] yr hen Oesodd' [sic]', 'englynion' between 'Colwyn' and 'Craff' ('gwaith brus mawr. Evanvs Thomasvs'), 'geiriau gwir Taliessin', and a numbered series of medical recipes headed 'Cynghorion amriw ddolurie'. There are also memoranda giving the date of birth of some of the children of Thomas Lewis and Margratte [sic] Evanes, etc., and some accounts [?Penllyn district, Merioneth].

Two notebooks in the autograph of John Jones ('Myrddin Fardd') containing transcripts of 'cywyddau', etc. by the following poets: Wiliam Llyn, Huw Llyn, Morys Dwyfech, Lewis Daron, Sion Wyn Owain, Kadwaladr Kesel, Huw Machno, Edmwnd Prys, Sion Philipp, Gruffydd Phylips, Huw Pennant, Lewis Menai, Wiliam Kynwal, Rissiart Philip, Richard Kynwal, Rhus Kain, Howel Reinallt, Sion Brwynog, Watkin Klewedog, Morgan ap Huw Lewis, Inco Brydydd, Dafydd Na[n]mor, Gruffudd Grug, Iolo Goch, Owain Waed da and Llywelyn Goch ap Meurig hên. Nearly all the poems are eulogies of, or elegies on , persons from Llŷn and Eifionydd. On the first page of MS 507 is the following note by J. H. Davies: 'Codwyd o lawysgrif Mr J. Glyn Davies ? Gan Myrddin Fardd' and it seems probable that the contents of MS 507 and the first ten items in MS 508 were transcribed from J. Glyn Davies MS 2 (though not in the same order), perhaps with a view to publication. The remaining poems appear to have been transcribed from various sources, including Cwrtmawr MS 454. Pasted in after the poems in MS 508 are two newspaper cuttings relating to 'Phylipiaid Ardudwy'.

A collection of poetry almost entirely in free metres entitled 'Casgliad o Gerddi a Charolau ar amryw Destynau O waith amriw Feirdd Cymru'.
