"This parish, anciently called Handmere, takes its name from a spacious mere, or lake, in form resembling a human hand, on one side of which the village is pleasantly situated. This fine sheet of water covers a space of seventy-three acres, and derives a great deal of picturesque beauty from the rich woodlands in its immediate vicinity, interspersed with highly cultivated eminences. .... The situation of the village, and the appearance of the country around it, are strikingly beautiful."
[ A Topographical Dictionary of Wales, S. Lewis, 1834]
