A pedigree in roundlets, evidently copied from a roll, from Beli Mawr to Cynan ab Iago of Gwynedd, Tewdwr ab Einion of Deheubarth and Bleddyn ap Cynfyn of Powys (ff. 13-23 verso); an armorial in Welsh, of Pum Brenhinllwyth Cymru and other Welsh arms, painted, two to the page (ff. 24-80). All in the hand of Wiliam Llŷn. Above many of the arms in the armorial the name is written in pencil by a contemporary hand, not that of Wiliam Llŷn. On ff. 81 verso-86 verso are additions in the hand of Siôn Cain. Folios 1-12 verso and 87-102 are blank. The index on ff. 103-106 verso is in the hand of Robert Vaughan.
