A volume [in the hand of Sir Samuel Rush Meyrick], the first part of which ( pp. 1-322) consists of an incomplete, heraldic dictionary, purporting to contain descriptions of 'The Arms of the gentry of Wales, and some others of the English gentry who match'd in Wales, alphabetically layd down'. Some of the descriptions are illustrated with pencil sketches of armorial shields, and a few of these have been coloured. A holograph note by S. R. Meyrick, on a fly-leaf at the beginning of the volume, reads 'The following Manuscript was copied from another, written about the latter end of the 16th, or beginning of the 17th century; and is an authentic heraldic compilation. The coats of Arms were not added to the original'. The second part of the volume (pp. 323- ) appears to have been intended as a biographical dictionary of the persons and families included in the first part ('Annotations on the foregoing heraldic Manuscript'). An incomplete list (A-L) of the said families and persons was compiled, but only in a comparatively few instances have notes been added.

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 A copy of an unpublished account, [1990s], of the Lewis family of Gilfach and Llwyncelyn, including references to the Pedigree Books, is now NLW ex 2511. An index to these two volumes is now NLW MS 23968i-iiE.
