MORDRYDD, a hamlet, in the parish of LLANSPYTHID, hundred of DEVYNOCK, union of BRECKNOCK and county of BRECKNOCK, SOUTH WALES, 2 miles (S. W.) from Brecknock; containing 138 inhabitants. It is situated in the upper part of a vale, the river Tarell separating it from the hamlet of Llanspythid, and at the northern declivity of the Green Mountain. At some distance to the south, and partly within the hamlet, rise the rocky and elevated conical mountains called the Brecknockshire Beacons, to the height of two thousand eight hundred and sixty-two feet above the level of the sea. A few males and females are gratuitously taught in a Sunday school by Particular Baptists. Gilbert Court, an old mansion built by some members of the family of Parry, in the reign of Elizabeth, near the southern bank of the Tarell, is now a farmhouse. Here is also situated DOlgoed, which formed part of the estate conferred by Bernard Newmarch on his follower, Sir John Skule; but not a vestige of the mansion occupied by the knight is now visible; though on a farm called Cilwhibarth is a large , mound or barrow, which Mr. Jones is of opinion was the " mons placitorum" of the manor. The rateable annual value returned for the hamlet is £874. A sum of £107 is the amount of the commutation for the tithes, of which two-thirds are payable to the impropriator, and one-tbird is received by the vicar of Llanspythid.
