Trefonen Church, which is capable of containing about 500 persons, was built on a piece of land given for that purpose by the late Sir W. W. Wynn, father of the present Baronet. It was originally intended that the service of this church should be wholly in Welsh; but, owing to the increase and prevalence of the English language, that intention was not persevered in, and the service has for some years past been performed in Welsh and English alternately. A substantial school-room, with a house for the Master, was erected in the year 1825, upon a portion of the glebe given for that purpose, with the sanction of the Bishop, by the late Incumbent, the Rev. Edward Jones, and which has been of great advantage to the district. The living is a perpetual curacy, in the patronage of the Earl of Powis. The present Incumbent is the Rev. D. Lloyd. Trefonen abounds in mineral wealth. Coal was raised in considerable abundance some years since in the adjoining township of Treferclawdd, but the pits there are now exhausted. It is still worked, however, in the township of Treflach, where there are also valuable and extensive quarries of lime. A mine was opened some years since in the Moelydd, which produces lead and calamine. RHYDYCROESAU CHURCH. In addition to the above means of providing church accommodation to the inhabitants of the parish, an additional advantage has been gained by annexing the two Welsh townships of Pentregaer and Cynynion to the new church at Rhydycroesau. This church is situated on the high road to Llansilin, about three and a half miles from the town of Oswestry. It owes its foundation to the Rev. G. N. K. Lloyd, late Rector of Selattyn, who contributed liberally himself, and, with the co-operation of the first and present Incumbent, the Rev. Robert Williams, M.A., raised a sufficient fund, by voluntary contributions, to complete the church and erect a glebe-house. The church was consecrated August 2nd, 1838, by the Bishop of St. Asaph, and the glebe-house was built in 1840. It is a Consolidated District Church, licensed for all parochial purposes; and has a legally-assigned district, consisting of the townships of Cynynion and Pentregaer, in the parish of Oswestry; a detached portion of the parish of Llanyblodwel, called Cefnymaes; with portions of the parishes of Llansilin and Selattyn. A very neat Gothic building has also been erected by the present Incumbent, aided by voluntary contributions, and opened as a National School in January, 1850. The sites for the school and playground, as well as for the church and church-yard, are the munificent gifts of Sir Watkin Williams Wynn, Bart. The portion of the population of the parish of Oswestry thus transferred to the district of Rhydycroesau is about 200.
