A late seventeenth century manuscript, the first page inscribed 'The Pedigree of Rice Vaughan, Esq., one of the Auncients of Grayes Inne, . . . since his death completed . . . and drawn down to Henry, his eldest son, . . . being a Curious peice of Antiquitye Collected out of many Ancient manuscripts by . . Robert Vaughan of Hengwrt . . . with severall Collections since made by Henry Va[ugha]n'. Pp. 19-214 contain descriptions and illustrations, some emblazoned, of the coats of arms of the ancestors of the aforesaid Rice Vaughan [of Gelli-goch, co. Montgomery, and later of Gray's Inn, lawyer and author of, inter alia, Practica Walliae or the Proceedings in the Great Sessions of Wales (London, 1672)]. The descent of the said Rice Vaughan and of Henry, his son, in direct line from each of these ancestors is shown, and historical notes have been added in some instances. The Rice Vaughan pedigree had been compiled in the first instance by the Welsh antiquary Robert Vaughan of Hengwrt, the work being completed circa October 1652, and this material was utilised and presented in book form in the present manuscript by Rice Vaughan's son Henry who added his own name to each line of descent (see the inscription quoted above, a transcript of a letter from Robert Vaughan from Hengwyrt (sic), to Meredith Lloyd in London, 25 October 1652 (pp. 11-15), a copy of an inscription at the end of the original pedigree by Robert Vaughan (p. 223), and notes by Henry Vaughan on pp. 17 and 222-3). According to the notes on pp. 17 and 222-3 it would appear that the material to be found at the beginning of the volume (i.e. up to the end of p. 10) and at the end (p. 224 et seq.) was compiled by Henry Vaughan. This includes, inter alia, genealogical and heraldic data relating to the Vaughans of Corsygedol [co. Merioneth], the Vaughans of Macchenlleth (sic) [co. Montgomery], the Hydes of Cheshire (to which family Henry Vaughan's wife belonged), and Henry Vaughan himself and his connection with 'seuerall eminent familyes in Wales'. Tipped in at the end of the volume is an undated letter from George Agar Hansard to a Mrs. Edwardes relating to the contents of the volume.
