Ffeil Peniarth MS 140 [RESTRICTED ACCESS]. - Achau teuluoedd De Cymru,

A collection of south Wales pedigrees in the hand of Wiliam Llŷn, written with greater care, and earlier perhaps, than most of his surviving genealogical manuscripts, with use of red and green. Up to p. 178 he is assisted by two other hands: Huws’ X130, making frequent short stints, often completing pedigrees begun by Wiliam Llŷn (e.g. pp. 15-17, 19, 24-7, 28, 30-5), and Huw Llŷn (pp. 162-3, 169-71, 176, 178). Another hand appears on p. 173 and another on p.177. From p.179 there is one assisting hand, Huws’ X131 (e.g. pp. 223-5, 240-1, 243-4). On pp. 372-7, ‘Gohelyth Glyn Nedd’, etc., signed ‘R T’, 1573, is added in the excellent hand of Richard Thomas of Ynysarwed. The latter part of the manuscript is written in Wiliam Llŷn’s increasingly untidy hand; use of red ceases after p. 318. Written not before 1561 (p. 212). On p. 8 in his later hand is ‘Henwau y pedair kamp ar ugain’. Pages 358-67 are in the early hand of Rhys Cain; there are additions in his mature hand on pp. 121, 224 and 324. On p. 1 is Robert Vaughan’s title: ‘Llyffr o Iachau Deheubarth o law Wiliam Llyn’ and on f. iv, ‘D. W. ll. llyfr Wm. Llyn am ddeheubarth’. On this compilation, see P.C.
