LLYWELYN FAWR and LLYWELYN FYCHAN ( fl. early 13th cent. ).

The sons of Maredudd ap Cynan . In spite of the breach between their father and Llywelyn I , they were friendly towards Llywelyn from 1215 onwards. The lordship of Merioneth , lost to the family in 1202 , may indeed have been restored to them as early as 1221 . Though they were confirmed in possession of the ‘cantref’ by Henry III in 1241 , both fought on the side of Dafydd II in 1245 . After that date there is no further mention of either of them.

In 1255 the death is recorded of Maredudd , lord of Merioneth , almost certainly the son of the elder Llywelyn . With the expulsion in 1256 of the latter's son, also Llywelyn , for treachery against Llywelyn II , Merioneth passed finally out of the possession of the descendants of Cynan ab Owain Gwynedd . Madog , the son of this last Llywelyn , was the rebel leader of 1294 .
