Nodiadau ynglŷn â therfysgwyr Beca a'r terfysgoedd gan William Chambers, yr ieuaf (heb eu dyddio).

Disgrifiad gan Evan D. Jones: '1. Bill Williams who was working with Shoni in Mr. Newman's pit was in the row at Goring Thomas's keeper. 2. Griffith of Penlan attended all meetings, night and day. He gave deponent (? Shoni) money which was subscribed to pay Hugh Williams for the meeting at Mynydd Mawr. It was 2/10. He told deponent to come in Becca's dress and demand the money. 3. The stout young butcher at Llanelly put some money in his own pocket. 4. The letter sent to Mr. Chambers and Mr. Rees was sent by 'Davy', who had a sore leg, living somewhere near the 5 roads. Had something to say to Margaret of the 'Stag and Pheasant', perhaps Stephens of Gellyfawr. 5. The worst men in the Beccas: Evan Gellyhir, Tom Morris, John the shoemaker, Morgan Saunders, and Davy of Kilverryucha.'
