Cemais (Dyfed)

[6] In the mid 11th century, Dyfed was part of Deheubarth ruled by Rhys ap Tewdwr who had accepted the suzerainty of William the Conqueror following the Norman Conquest of England.

[9][10][11] According to local tradition recounted by Richard Fenton, following a skirmish at Morvil, de Turribus was victorious and violent towards the inhabitants he encountered.

His son, William Fitz Martin, received Kemes as a dowry when he married Angharad, a daughter of Rhys ap Gruffydd.

[15] When war broke out upon Rhys's death in 1197, between Maelgwn and Gruffydd, William fitz Martin re-established his control of Kemes, founding a new caput at Newport; the eventual victor of the war—Maelgwn—did not displace him.

Kemes remained with William's descendants during the 13th century; even though it was captured by Llywelyn Fawr in 1215 and his grandson in 1257, on both occasions the Fitz-Martins successfully recovered it.

[17] In 1326, two years after his similarly named father, the reigning Lord Martin (the Fitz having been dropped earlier in the previous century) died childless, and the Lordship was inherited by his sister, Joan, and her husband, James Audley.

In 1534, Henry VIII transferred the lands from the crown to John Tuchet, 8th Baron Audley, as an English feudal barony.
