A volume containing a glossary of armorial families and individuals; a few pedigrees, notably of Griffith of Carreg-lwyd, Llanfaethlu; a list of the fifteen tribes of North Wales; and a note and diagram to ascertain the acreage of the island of Anglesey.

A volume, [16 cent., second ½], probably in the hand of Thomas Powell (d. 1588), Parc y Drewen, Whittington, co. Salop, containing a much shortened text of Humphrey Lhuyd's English version of Brut y Tywysogion, upon which version David Powel based his Historie of Cambria, now called Wales ... (London, 1584) (see Brut y Tywysogion ..., ed. by Thomas Jones (Cardiff, 1952), pp. xiv-xviii). Omissions mainly involve passages relating to events outside Wales, church affairs and the papacy, anecdotes, explanations of Welsh personal and place-names, and the arguments against Polydore Vergil. Three other copies are known: BL, MS Cotton Caligula A VI; Oxford, Bodleian Library, Ashmolean Museum MS 847; and NLW, Llanstephan MS 177. Also included are a pedigree of the kings and princes of North Wales from Cadwaladr to Llywelyn ap Gruffudd (ff. iv-v verso), a painted coat of arms of Cadwaladr (f. 1), and an index of personal and place-names (ff. 168-70 verso). Six lines of English verse are added in a contemporary hand on f. 171 verso.
