The manor of St. Winnuc or St. Winnow had already passed to a sub-tenant at the time of the Domesday Survey, and the impropriated tithe and advowson of the church of St. Winnow to the dean and chapter of Exeter, before 1291. There is nothing to suggest the source whence the manor was obtained for the endowment of the bishopric, save that St. Winnow adjoins Lanhydrock, which belonged to St. Petrock, and may, therefore, have been taken from the saint. The manor of Tinten in St. Tudy, held in 1086 by Richard, of the bishop, was not considered worthy of separate mention in the _Taxatio_ of 1291. It is the only episcopal manor the name or locality of which does not suggest an ecclesiastical origin. The advowson of St. Tudy was independent of it being appendant to the manor of Trethewell in St. Eval. Does the half hide of Tinten represent the lay contribution of Cornwall towards the endowment of the see of Exeter?[72] We are now in a position to summarise the results of the foregoing survey. We have seen that the Cornish possessions of the see of Exeter, at the time of the Domesday Survey, consisted chiefly of manors which had St. Germans, Lawhitton, Pawton and Penryn (or Tregear) for their centres. St. Germans and Pawton, and probably Lawhitton, were derived from monastic sources, viz. from the monasteries of St. German, St. Petrock, and probably from St. Stephen. The possessions in and around Penryn require further examination. That there was a monastery-bishopric at Dinurrin or Dingerein in the ninth century is clear from Kenstec’s profession of obedience to Archbishop Ceolnoth. To treat of Gerrans and its associations in an impartial spirit is wellnigh impossible. Legend, history and fact are so strangely and so suggestively interwoven that the temptation is equally great to say too much or too little. The name Gerrans is a modern form of Geraint or Geruntius. The presence of Gerrans, Just and Cuby, as the names of three churches and parishes near together, is indeed a remarkable coincidence if they are not identical with Geraint of Anglesey, his son Jestyn or Just, and his grandson Cuby, son of Selyf. No valid reason has been offered against the identification. Mr. Baring-Gould considers St. Gerrans the same person as Gerennius, King of Cornwall, who requested St. Teilo to visit and communicate him when dying (circa 556).
