Anfonwyd y copi hwn o'r penderfyniadau a basiwyd mewn cyfarfod o blwyfolion Llanelli ar Fynydd Sylen, 17 Awst 1843, at R. Goring Thomas gan William Chambers. Cadeiriwyd y cyfarfod ar 17 Awst gan William Chambers.

Disgrifiad gan Evan D. Jones:

'The chairman be requested to forward to Mr. R. G. Thomas a copy of the resolution passed on Mynydd Sulen. With regard to the 1s., Mr. Chambers having reported that Mr. Thomas expressed his intention of returning it to him and his tenants, they considered themselves entitled to the same and represented most strongly the injustice of his demanding it in future arising as it did from a mistake of Mr. Thomas's own agent. Meeting adjourned to 21 September.'
