Roger de Clare:

Born AFT 1115
Died 1173
5th Earl of Clare, 3rd Earl of Hertford

Richard's youngest son Roger, who succeeded his father as earl in 1152, also campaigned in Wales and either built or reconditioned a number of strategic castles, including:
Castell Hywel: Between Lampeter & Newcastle Emlyn. Destroyed by the Welsh in 1136 and rebuilt in 1153.
Aberdyfi (Aberdovey)
Dineirth: A motte-and-bailey castle near Aberystwyth destroyed in 1208. Some signs of masonry.
Llanrhystud
Most of the castles above have long since disappeared from the landscape, however, another branch of the de Clare family (the junior branch) was to leave an even more indelible mark on castle building in Wales. Indeed, many claim that Gilbert de Clare's masterpiece at Caerphilly represents a major turning point in castle design and construction in Britain.
