MINERA, a chapelry (extensive), in that part of the parish of WREXHAM, which is in the hundred of BROMFIELD, union of WREXHAM, county of DENBIGH, NORTH WALES, 4 miles (W. by N.) from Wrexham; containing 628 inhabitants. The chapelry comprises the western portion of the parish, which is hilly, and abounds with mineral wealth, from which circumstance the present name is supposed to be derived: its ancient appellation was Mwyn-Glawdd, or " the mine upon the ditch," in allusion to Offa's Dyke, that passes through it. It is bounded on the north by the river Alyn, which rises in this district. The greater portion of the inhabitants are engaged in the mines, consisting of iron, lead, and coal, the last wrought to a considerable extent; but the lead-mines are at present discontinued, owing to the influx of water, and, though seven steam-engines and a mill have been employed in clearing them, the attempt has hitherto proved unsuccessful. The rateable annual value of the township has been returned at £960. The living is a perpetual curacy, united to that of Bersham-Drelincourt, and endowed with £200 private benefaction, £400 royal bounty, and £800 parliamentary grant: the chapel is a small cruciform structure. There are three Sunday schools, connected with the dissenters, which afford gratuitous instruction to about one hundred and sixty males and females.
