An imperfect, composite manuscript consisting of transcripts, in a number of hands of the late sixteenth and seventeenth centuries, of miscellaneous prose and verse items including Welsh poems in strict metre by Edward Dafydd, Dauudd Edward, Davydd William, 'viccar Penllin', Lewis Mfln, Thomas ap Rys 'o blas jolyn', Phillipp Pwell, John Tudur, Dauidd ap Gwilym, Robin Ddv, Gruffydd ap Iefan, John Philipps, Iolo Goch, Thomas Derllysc, Gruffydd Gryg, Siôn Cent, Richard Kynnwal, Huw Machno, Robert Dyfi, and Kadwalader Kesel, two versions of the code of rules for regulating the craft and conduct of the Welsh bardic order generally attributed to Gruffudd ap Cynan, a copy of 'The order of the funerall of John Conway of Botruthan in the Countie of Flint, Esquier, who was intered in Rithlan the 23th of December 1606', a prophesy entitled 'The prophesie of Gre[ ]' (Latin), and a short sequence of Welsh triads. Some of the leaves bear contemporary foliation indicating that they formed sections of other manuscripts. An inscription in the hand of Edward Williams (Iolo Morganwg) on the previous upper cover lists the contents of the volume, and, from this list, it appears that a section containing an account of Gruffudd ap Cynan's sojourn in Ireland in 1098 ('Hanes Gruffudd ap Cynan yn y Werddon yn y flwyddyn 1098') has been lost since the time the inscription was written. There are a few marginal annotations by Iolo Morganwg.

Pedigree and achievement, 1591, of Francis Vaughan (Vychan or Vichan, d. 1597), of [Sutton-upon-Derwent], Yorkshire, compiled by Thomas Jones (Twm Siôn Cati) of Fountain Gate, Cardiganshire, and probably executed by Richard Adams 'paynter of Ludlow' (c.f. NLW Roll 226), with fifty-three fully painted coats of arms, mostly impaled and many quartered.
The pedigree is traced from 'Kradog Vraychvras, Earle off Herefourde', 'Iustyn ap Gurgan, K[ing] of Glamorgan & Morganog', 'Ryes Tewder [Rhys ap Tewdwr], King off Southwales', 'Griffith ap Kynan, King off Northwales', and 'Bleddyn ap Kynvin, Prynce off Powys', as well as from Edward I. Additional information is enclosed in twelve cartouches, mostly scattered throughout the top third of the pedigree, with one each in the bottom corners. The pedigree most closely resembles 'Style 1' in Michael Powell Siddons, Welsh Pedigree Rolls (Aberystwyth, 1996), p. 11. Vaughan's grandfather was Thomas Vaughan of Porthaml, Talgarth, Breconshire; the family's association with Yorkshire began only with Francis's father, John, who settled there early in the reign of Elizabeth I. Francis Vaughan was chief steward of crown lands in the East Riding from 1580, High Sheriff of Yorkshire, 1594-95, and was killed in Ulster, in service to the crown, in July 1597.

Transcripts, begun in 1683, of Sir John Wynn, History of the Gwydir Family taken from 'a Coppy belonging to Sr Morris Parry of Llan Elian Clerk, in the year 1674 and afterwards compar'd with & corrected by two Coppys, the one Belonging to the Reverend Dr Humphreys Dean of Bangor, the other found among the Evidences att Gwedir, which last was in many places corrected & interlin'd, & much of it writt with the hand of Sr John Wynn himselfe the author'; 'Ystoria Gruffudd ap Cynan ...' copied for Thomas Mostyn, Gloddaeth, 1683, from 'Llyfr Plas-y-ward'; 'a chronicle supos'd to be collected by Robert Vaughan of Hengwrt ...'; charters, indentures, petitions, etc.

A manuscript, 1774, in the autograph of Evan Evans (Ieuan Fardd) containing triads (pp. 7-57, 65-66); the Life of Gruffydd ap Cynan (pp. 75-160); etc.
On p. 1 is a list of contents, stated to have been copied from the library of Watkin Williams Wynn. The text of the Life of Gruffydd ap Cynan, including notes, printed in Myvyrian Archaiology of Wales Vol. II, pp. 582-605, is taken wholesale from this manuscript.

Colour illustrations of armorial bearings, seals, memorial inscriptions and memoranda relating to the Wynn of Gwydir family added to a copy of Sir John Wynn, The History of the Gwydir Family (Ruthin, 1827). Inserted on f. 11 are two original items in the hand of Sir John Wynn, one of which is a transcript of a letter from Henry III to Llywelyn ab Iorwerth.

A composite volume containing miscellaneous transcripts, extracts, notes, etc., in the hand of Edward Williams ('Iolo Morganwg'). Pp. 1-60 contain a copy of the medieval Welsh metrical treatise or bardic grammar which is usually attributed to Einion Offeiriad and/or Dafydd Ddu o Hiraddug. In the present version which, according to a note on p. 61, was transcribed [by Edward Williams] from manuscript texts then in the possession of Mr. [Thomas] Richards of Llangrallo [co. Glamorgan] and the Reverend Thomas Evans of Brechfa [co. Carmarthen], the work is, however, attributed to Edern Dafod Aur. For the probable source of the present text, subsequent transcripts made of it, its attribution (probably by Edward Williams) to Edern Dafod Aur, and its connection with the version published in John Williams ('Ab Ithel'): Dosparth Edeyrn Davod Aur . . . (Llandovery, 1856), see the introduction to G. J. Williams ac E. J. Jones (gol.) : Gramadegau' r Penceirddiaid (Caerdydd, 1934), p. xv, and J.
