The native dynasty of Maelienydd, the upland between the Ithon and the Teme.
Roger Mortimer, whose father's men killed Cadwallon ap Madog in 1179, invaded with royal troops in 1195 and rebuilt Cymaron; by 1200 he holds the land. The family is in exile or in the hills, and comes back after 1212 under Llywelyn's protection.
