Roger Mortimer of Wigmore
Roger de Mortimer (before 1153-before 8 July 1214) was a medieval marcher lord, residing at Wigmore Castle in the English county of Herefordshire. He was the son of Hugh de Mortimer (d. 26 February 1181) and Matilda Le Meschin.
Roger would appear to have been of age in 1174 when he fought for King Henry II against the rebellion of his son, Henry. In 1179 Roger was instrumental in the killing of Cadwallon ap Madog, the prince of Maelienydd and Elfael, both of which Mortimer coveted. He was imprisoned until June 1182 at Winchester for this killing.
- Hugh de Mortimer (d.1227) - married Annora (Eleanor) de Braose, daughter of William de Braose and his wife Maud.
- Ralph de Mortimer (d.1246).
- Philip Mortimer
- Joan Mortimer (d.1225) - married May 1212 to Walter de Beauchamp
He is often wrongly stated to have been the father of Robert Mortimer of Richards Castle (died 1219) - married Margary de Say, daughter of Hugh de Say. This Robert was born before 1155 and therefore could not have been a son of Roger.
Lord of Maelienydd
In 1195 Roger, with the backing of troops sent by King Richard I invaded Maelienydd and rebuilt Cymaron Castle. In 1196 he joined forces with Hugh de Say of Richards Castle and fought and lost the battle of New Radnor against Rhys ap Gruffydd, allegedly losing some forty knights and an innumerable number of foot in the fight. By 1200 he had conquered Maelienydd and issued a new charter of rights to Cwmhir Abbey. In the summer of 1214 he became gravely ill and bought the right for his son to inherit his lands while he still lived from King John. He died before 8 July 1214.
