family, the heiress of which Joan Bittlesgate, daughter of Thomas (or John) Bittlesgate by his wife Joan Beauchamp, was the wife of Richard Woodville (died 1441), grandfather of Elizabeth Woodville (c.1437-1492) Queen consort of England as the spouse of King Edward IV.
In 1381 the Bittlesgate family obtained a licence from the Bishop of Exeter to build and operate a private chapel at their home, but no trace of the structure survives.
[7] As all the grandchildren of Thomas III Bittlesgate died childless, in accordance with the entail the estates descended to the great heiress Lady Cecily Bonville (1460-1529), wife of Thomas Grey, 1st Marquess of Dorset (1455-1501), the son of Elizabeth Woodville by her first husband Sir John Grey (c.1432-1461) of Groby in Leicestershire.
[9] Following the attainder of Cicely's grandson Henry Grey, 1st Duke of Suffolk (1517-1554), his estates escheated to the Crown, which sold Knightstone to William Sherman, a wealthy merchant[10] of Ottery St Mary.
[11] Three monumental brasses of the Sherman family survive in Ottery St Mary Church, at the east end of the south aisle, one dated 1542, another 1583.
