Disgrifiad gan George Eyre Evans (cyfieithiad):

"Ysgrifennwyd y llythyr hwn ychydig oriau wedi ymweliad 'Rebecca a'i phlant' â phentref Llanddarog, ger Caerfyrddin, lle cafodd tollborth ei ddinistrio gan dorf o tua 500 o bobl gyda gynnau, cleddyfau a cheibiau. Wedi dinistrio'r porth hwn, symudodd y dorf ar unwaith i borth Troed-y-rhiw a wynebodd dynged debyg."

Adysgrif:

"Carmarthen, 1 July, 1843.

My dear Sir,

I have received your letter, and I regret exceedingly these outrages continue in your neighbourhood. I am much obliged to you for the information you have given me, and I hope you will be enabled to ascertain the part of the country from which these people come. I shall be here all Tuesday till 5 in the afternoon, unless I am called away suddenly. I go to St. Clears on Wednesday.

I am, very truly,
Geo. Rice Trevor.

After the receipt of your letter tonight, I shall not expect you on Tuesday. This was written earlier.

I am glad you have got a clue, which I hope you will succeed in following up."
