LLANGENNECH (LLAN-GENNECH), a parish, in the union of LLANELLY, hundred of CARNAWLLON, county of CARMARTHEN, SOUTH WALES, 4 miles (E. N. E.) from Llanelly; containing 893 inhabitants. This parish is situated on the western margin of the river Loughor, by which it is separated from the county of Glamorgan; and is intersected by the rivulet called Morlais, a tributary to that stream, and also by the turnpike-road from Swansea to Llanelly. The surface is varied; the lands for the greater part are inclosed and cultivated, and the soil is generally fertile. The surrounding scenery is pleasingly diversified; and within the parish is Llangennech Park, formerly the property of the Stepneys of Llanelly House. Coal of very superior quality, which obtains a high price in the London market, is found in the parish; and works upon an extensive scale have been established by the Llangennech Coal Company, who, in addition to the fine beds discovered on the Park estate, have recently opened new pits of coal, and also of culm, of which considerable quantities are exported. The river Loughor is navigable at spring tides, for vessels of two hundred tons' burthen, to the quay belonging to the Coal Company, who have greatly improved it, and rendered it very commodious; they have also lately constructed a railway to, and a floating-dock and other works at, Llanelly, which are described in the article on that town. Two fairs are held annually on June 16th and October 23rd, in the village. The living is a perpetual curacy, endowed with £200 royal bounty, and in the gift of Edward Rose Tunno, Esq., of Llangennech Park, who is also impropriator, and who has lately augmented the income of the benefice, previously £82, with a farm producing £40 per annum. The church is dedicated to St. Gwynog. There is a place of worship for Independents; and a day school, commenced in 1831, contains 50 children of both sexes, and is supported by Mr. Tunno.
