Claim: Owain Fychan lost control in Mechain, Cynllaith, Caereinion and Mochnant Is Rhaeadr, so he was only able to sell Carreghofa Castle in 1187.
Evidence: Owain Fychan now controlled Mechain, Cynllaith, Caereinion and Mochnant Is Rhaeadr. Carreghofa Castle was retaken by Henry II in 1165, but Owain Fychan had recaptured it again by 1187.
