Edmund, seventh lord, eldest surviving son, succeeded, and commenced his career by attacking the Welsh at Builth, and receiving and transmitting Llewelyn’s head to the king. As some suspicion attached to his loyalty owing to his Welsh blood, he was particularly active in quelling the disturbances that followed on the death of the prince, and it was in putting down one of them in 1303–4, also at Builth, that he received a wound of which he soon after died at Wigmore.
Roger, eighth lord, styled Lord Mortimer of Wigmore, created Earl of March in 1328; served both in Ireland and Scotland. He was governor of Builth Castle, took Cardiff from Hugh le Despenser, and had a grant of Clun. He joined the party of Thomas of Lancaster against Edward II., had a narrow escape for his life while in prison, and in gratitude built St. Peter’s Chapel in the outer ward of Ludlow Castle. In 1322, after the battle of Boroughbridge, he fled to France, and the king seized on Wigmore, causing an inventory to be drawn up of its contents by John de Cherleton, the keeper. There were springholds, the artillery of the age, cross-bows, English and Oriental armour and weapons, a chess-board and a board for talles and draughts, five peacocks in the courtyard, and grain and cattle in quantity. On the earl’s return, followed his intimacy with the “she-wolf of France,” his acquisition of a prodigious number of manors in England, Wales, and Ireland; his seizure at Nottingham Castle, his attainder, and his execution by hanging in 1330. It seems probable that this lord rebuilt the castle, superseding the Norman work by that, in the Decorated style, which still remains.
Edmund, his son, did not recover the earldom. He died young, a few months after his father, in 1331, leaving a son, a minor.
Roger, tenth lord, who succeeded, had livery of Wigmore Castle before he came of age. He obtained the reversal of the attainder and the restoration of the earldom of March in 1352. He served Edward III. in France, recovered much of the Welsh property, including Ludlow and other estates coming by his grandmother, the heiress of Genville; and finally died 1360, being then commander of the English forces in Burgundy.
Edmund, eleventh lord and third Earl of March, his son, succeeded. His abilities were early turned to account by Edward, who employed him while under age in negotiating a peace with France, and afterwards as Lieutenant of Ireland. He married Philippa, heiress of Lionel, Duke of Clarence, and thus maintained the ancient honours and influence of his name. He died at Cork 1381.
Roger, his eldest son, became fourth Earl of March. He was by Richard II. made Lieutenant of Ireland, and by descent from the Duke of Clarence declared heir of the Crown. His service was entirely in Ireland, where he was slain. He was followed by Edmund, his son.
Edmund, fifth and last Earl of March, was regarded with excessive jealousy by Henry IV., as heir to the throne, and was kept, during his reign, under surveillance. Henry V., however, employed him in Normandy, and in the next reign he, like his immediate forefathers, became Lieutenant of Ireland. He died 1425, aged twenty-four years, and with him ended the male line of Mortimer of Wigmore.
Among the castles returned as held by him, at his death, in the Marches, were Blaenlevenny, Builth, Clifford, Dinas by Talgarth, Dolveren, Denbigh, Knoclas, Kevenles, Ludlow, Montgomery, Norton, Nerberth, Raidrey, Radnor, Usk, and Wigmore.
Richard, Duke of York, as his sister’s son, was heir of the vast estates of the Mortimers, and transmitted them to his son, Edward IV., when all became merged in the Crown. It was from the Honour of Wigmore that Edward raised most of the power that enabled him to defeat Owen Tudor at no great distance from the castle, and still nearer to Mortimer’s Cross. The castle remained in the Crown till granted away by Elizabeth. In 1601 it was purchased by Thomas Harley, and in 1643 dismantled by the Parliamentary forces, since which it has been a gradually diminishing ruin.
