TREVLYN, a hamlet, in the parish of TatGARON, upper division of the hundred of PENARTH, county of CARDIGAN, SOUTH WALES, 2
miles (N. by E.) from Tregaron; containing 180 inhabitants. It is situated near the Teivy, on the left bank of which,
between this place and Tregaron, is a bog of excellent peat; and higher up is a beautiful lake, about three-quarters of a
mile in circuit, called Llkn y Maes, or " the lake of the field," from which the hamlet takes its name, and which
tradition states to cover the original site of the town of Tregaron. An old Roman road from Loventium to the northern
parts of the county passed through the hamlet; and the remains, consisting of a bank of raised earth, are still visible.
