"A parish in the Union of Oswestry, principally in the Cynlleth division of the hundred of Chirk, county of Denbigh, extending also into the English county of Salop, in which it comprises the township of Sychdin. ..... This parish, which is eight miles in length, and averages about seven miles in breadth, is finely situated on the river Cynlleth; the lands are enclosed and in a high state of cultivation, and the soil is fertile and productive: the surrounding scenery is richly varied, and the views over the adjacent country abound with interest and variety." [A Topographical Dictionary of Wales, 1833 & 1849, Samuel Lewis]
