Cedewain

It possibly consisted of the commotes (cymydau) of Cynan,[1] Hafren[2] and Uwch Hanes.

[4] It lay at the south of the kingdom, bordering with the cantrefi of Caereinion and Ystlyg to the north across the river Rhiw, and the cantrefi of Arwystli (subject to disputes between Powys and Gwynedd) and Maelienydd (originally an independent kingdom) to the south.

Maredudd ap Rhobert was Lord of Cedewain and Chief Counsellor of Wales when he died in 1244 after joining the religious order at Strata Florida Abbey.

They claimed to be the rightful heirs to the cantref and that it was seized from their ancestors by the Marcher Lord family of the Mortimers.

They said that Roger Mortimer had allowed them to keep some land between the River Severn and Ceri (the northern commote of Maelienydd), but Edmund had seized that too.
