LLANDUDWEN (LLAN-DUDWEN), a parish in the hundred of DINLLAEN, Lleyn division of the county of CARNARVON, NORTH WALES, 5 miles (W. by N.) from Pwllheli, containing 85 inhabitants. The lands in this parish, consisting of about one thousand one hundred and sixty acres, and having for the most part a clayey, though in some places a peaty and gravelly, soil, are generally low and flat, and form the most fertile and best cultivated tract, in this part of the principality. The surrounding scenery is varied ; and among the most striking of the objects which it comprehends is Carn Madrin, at the base of which, within the parish, and occupying a romantic situation, is Madrin, an ancient mansion, now the property and residence of T. P. J. Parry, Esq. The living is a perpetual curacy, annexed to the rectory of Rhiw, in the archdeaconry and diocese of Bangor. The church, dedicated to St. Tudwen, is a small neat cruciform edifice, in good repair. There are places of worship for Independents and Calvinistic Methodists. The average annual expenditure for the support of the poor is £ 51. 2. (A Topographical Dictionary of Wales by Samuel Lewis, 1833)
