"LLANDDEWI, or LLANDEWY, a parish in the hundred of SWANSEA, county of GLAMORGAN, SOUTH WALES, 14 miles (W. by S.) from Swansea, containing 150 inhabitants. A castle is said to have been anciently erected here, the reputed site of which is now occupied by a farm-house, in which some of the walls of the ancient building are reported to be incorporated : there are, however, no records either of the origin or history of the fortress. The living is a discharged vicarage, in the archdeaconry of Carmarthen, and diocese of St. David's, rated in the king's books at £3.3.4., endowed with £800 royal bounty, and in the patronage of the Bishop of St. David's, who is also impropriator of the tithes. The church, dedicated to St. David, is a small edifice. The parishioners of Knelston perform their various religious duties and ceremonies at this church, their own being in a state of dilapidation; and the vicar receives a small additional stipend from the chapter of St. David's, as a compensation for the additional duty. The average annual expenditure for the support of the poor amounts to £29. 18." ( A Topographical Dictionary of Wales by Samuel Lewis 1833)
