"TREFGARN (GREAT), a parish in the hundred of RHÔS, county of PEMBROKE, SOUTH WALES, 5 miles (N.) from Haverfordwest, containing 112 inhabitants. It is intersected from north to south by the Western Cleddy river, up the valley of which passes the turnpike road from Haverfordwest to Fishguard. The north-western part of it is composed chiefly of the Trefgarn and Leweston mountains, which form an elevated, heathy, and barren tract, unfit for cultivation. The most remarkable natural feature of its surface is that from which it derives its name, signifying "the town of the rock," and which consists of two rocks of striking aspect, rising abruptly to a considerable height above the moor, and presenting the appearance of ruined castles, an idea which seems confirmed to the eye by their being situated so as to command the narrow pass of the mountain through which the Western Cleddy here flows, and which, on the opposite eastern side, presents a fine grove feathering down to the water's edge. The portion of the parish lying to the east of the Cleddy is called Little Trefgarn. Trefgarn Hall, situated a little to the west of the village, is a modern seat, erected in 1824, by the present proprietor, Dr. Evans, and commands a fine and extensive view over the district of Rhôs.The living is a discharged rectory, in the archdeaconry and diocese of St.David's, rated in the king's books at £1. 13. 9., and in the patronage of Dr.Evans, who is proprietor of the whole parish. Some old encampments were formerly traceable here, but their defences have been levelled. The average annual expenditure for the relief of the poor amounts to £35. 10." [From A Topographical Dictionary of Wales (S. Lewis, 1833).]
