GARTH-BEIBIO, a parish, in the upper division of the hundred of MATHRAVAL, county of MONTGOMERY, NORTH WALES, on the road
from Welshpool to Machynlleth, Dolgelley, &c., 9 miles (N. W. by w.) from Linnvair, containing 342 inhabitants. This place
derives its name from Garth, a ness, or promontory, and Peibio, the name of some chieftain, of whom nothing is known. The
parish contains about one thousand six hundred acres of land enclosed and under cultivation, and nine hundred acres
unenclosed: it is situated between the rivers Twrch and Banwy, which unite just below the church: peat is procured
within its limits. The living is a discharged rectory, in the archdeaconry and diocese of St. Asaph, rated in the king's
books at £6. 1. 8., endowed with £200 royal bounty, and in the patronage of the Bishop of St.Asaph. The church is an
ancient structure, dedicated to St. Tydecho. Near it is St. Tydecho's well, constructed for a cold bath, the water being
considered efficacious in rheumatic and other disorders: formerly every one who bathed in the well, or drank the water,
dropped a pin into it, and it was deemed sacrilege to take any of them out. Divers bequests have been made for the benefit
of the poor, but they are of very small amount. There are several cairns in the parish. The average annual expenditure for
the support of the poor amounts to £91. 12.
