"Ricard holds of the Earl, Tiwardrai. Colo held it in the time of King Edward and it was taxed for one hide, nevertheless there are two hides: the arable land is twelve carneats: in Domain there are four carucates: seven bond servants and eight villains, and eighteen borderers, with three ploughs: there are six acres of wood and one hundred acres of pasture: formerly it was worth £4, now 40s". 11 cattle, 12 pigs, 100 sheep.
This Manor was bestowed by William I on his half brother Robert, Earl of Mortain, Earl of Cornwall.
Richard (Fitz Turold)had great possessions amongs which was the Manor of Tywardreath.
The Manor subsequently passed to Ricardus Dapifer and thence to Robert de Cardinham ( 1261-88) then sold in the latter part of the 13th Century by Isolde de Cardinham to the Champernownes for £100. It then passed to the Herles and Bonvilles and fell to Thomas Cromwell on the attainder of the Duke of Suffulk in 1554.
In 1620 it was bought with the great and small tithes by the Rashleigh family of Menabilly.
