A notebook marked 'Copy No 1' containing an account of the hundred of Eifionydd followed by the beginning of an account of the hundred of Llŷn or Lleyn and a note on 'Dinas a Llys Dinorwig' by Peter Bayley Williams, Llanrug (cf. Y Gwyliedydd, 1835, 310), this last in the autograph of John Jones ('Myrddin Fardd'). The material on Eifionydd bears a resemblance to 'Hanes Eifionydd' by W. Jones ('Bleddyn'), Llangollen (see Y Geninen, 1883, p. 59; 1884, pp. 69, 300) but the hand is probably that of 'Myrddin Fardd' at an early period of his life. Loose inside, pasted on a card, is a press-cutting concerning Enwau Lleoedd Sir Gaernarfon (see Cwrtmawr MS 564).
