An imperfect, ? early seventeenth century manuscript with, bound in at the end, a ? previous, brown-paper cover inscribed in a later hand 'Llyfr Achau Llangannau 1740'. The contents consist largely of miscellaneous genealogical data much of which relates to Glamorgan and South Wales. Ff. 51-2 contain a transcript, in a later seventeenth century hand, of a Welsh strict-metre poem not attributed to any poet. There are some marginal annotations possibly in the hand of Edward Williams ('Iolo Morganwg').

A volume containing mainly pedigrees of North and South Wales families written by two principal scribes of the circle of George Owen of Henllys, Pembrokeshire.
(a) Pages 1, 7-209, 223-232, 239-256 and possibly 372-373 are written by a scribe who, although experienced in penning a good secretary hand and in executing ornate headings, is often inaccurate in his transcription of Welsh personal and place-names; he also wrote the line 'Owain ap Gruffith /i/ gelwid Gwinn ap Gr: yn jawn' on p. 41, in italic (examples of the same italic hand are found in the margins of pp. 19, 66, 113, 355, 356, 361 and elsewhere). This section comprises a collection of pedigrees mostly of North Wales families, including 'Bonedd y Saint' (pp. 84-90); the prose text 'Pedwar Marchog ar Higen oedd yn llys Arthur' (end wanting) (pp. 37-38); the dates of battles in the 'Wars of the Roses' (pp. 31, 208); five englynion, including one by Richard Davies, bishop of St Davids (p. 1), and other englynion dispersed among the pedigrees (pp. 57, 78, 92, 114-115, 170), together with the series of forty englynion entitled 'Campod Manuwel' (pp. 223-232); and the prose piece 'Disgrifiad Arfau', a Welsh translation of the heraldic treatise 'Tractatus de Armis', attributed to John Trevor, bishop of St Asaph (pp. 239-256). The ultimate source of this section is the collection of pedigrees and other texts written, [c. 1510], by 'Syr' Tomas ab Ieuan ap Deicws in Peniarth MS 127 (see p. 53); however, internal evidence suggests that the scribe was copying from the transcript of Peniarth MS 127 in NLW MS 17112D rather than directly from the original (see p. 104, where he begins copying the note 'Darfu examinatio y llyfrev newydd hyd yma' which occurs on f. 66 verso of NLW MS 17112D, before he realized his mistake). Both Brogyntyn MS I.15 and NLW MS 17112D preserve the original order of the text of Peniarth MS 127, which has been subsequently disarranged in binding. (b) Pages 211-212, 269-371, 374-411 are written by another experienced scribe whose display script is almost indistinguishable from that of the first scribe. These pages contain pedigrees mostly of South Wales families and include two copies of 'Llyma enway Kwnkwerwyr y rhai a vyant yngwlad Vorgannwg ay harfay' (pp. 280, 361-362), a third containing merely a short list of the conquerors' names (p. 310), and two copies of 'Llyma achoed Saint ynys Brydain' [= 'Bonedd y Saint'] (pp. 363-365, 385-386). The text on pp. 211-212, as indicated by a note in the hand of George Owen of Henllys at the head of p. 211, was copied in 1596 from the manuscript of 'Hyw Lewis Sr morgan' of Hafodwen, Carmarthenshire, which 'D'd ap Ienkin m'edd o Vachynlleth' wrote in 1586; the original is now NLW MS 3055D (Mostyn MS 159), pp. 232-233. The text on pp. 271-343 is partly derived from a manuscript written in 1513 by the Carmarthenshire poet and genealogist Ieuan Brechfa for 'Mastr John ap Henry ap Rees', with some of the pedigrees brought down to the second half of the sixteenth century; Ieuan Brechfa's manuscript does not seem to have survived; it is not Peniarth MS 131, pp. 199-308, which is thought to be in his hand. The source of pp. 345-411 is unknown, although the text on pp. 347-365 follows very closely that in Peniarth MS 143, pp. [?1-3], 4, 47-48, 7-19, 33-46, 49-52, written by the same mid-sixteenth century scribe who wrote many of the religious texts in Cardiff Central Library Havod MS 22. A leaf containing a prophecy in English verse, written in a late-sixteenth century hand, has been tipped in after the main text (pp. 413-414).

The volume, which contains 'englynion', 'carolau' and pedigrees, is written for the most part (ff. 1-52 verso and 75 verso-101 verso) by Wiliam Dafydd Llywelyn of Llangynidr (c. 1520-1606) (cf.

A two-volume collection of pedigrees, mainly of South Wales families, compiled during the 1830s (23967iE watermark 1828; 23967iiE watermark 1831), with some later additions, by David Jones Lewis, Gilfach, Llanwrda, Carmarthenshire.
A duplicate set of these volumes, also written by David Jones Lewis, are the 8 volumes of Gilfach MSS in the College of Arms, London (see Francis Jones, A Catalogue of Welsh Manuscripts in the College of Arms (London, 1988), pp. 69-71), which are dated by colophon to 1830. This duplication is mentioned in a note, dated 8 July 1895, in 23967iE, p. 1, by Lewis's grandson, David Jones Lewis of Llwyncelyn, Llanwrda, who has also overwritten parts of the earlier text, as well as adding pedigrees relating to the Lewis family, [1895] (pp. 1438-50), and a copy of 'an account of the Lewis family in the handwriting of my late grandfather', 1896 (pp. 1494-6). There are minor additions relating to the Lewis family, to at least 1978, in several different hands (pp. 1438-41, 1448-50). A copy of an unpublished account, [1990s], of the Lewis family of Gilfach and Llwyncelyn, including references to the Pedigree Books, is now NLW ex 2511.
