Of these eleven manors all except five, viz. Burneir, Lanherne, Tinten, Lanisley, and St. Winnow, were demesne lands, the whole of their revenues going direct to the bishop. Richard Fitz Turold held Burneir and Tinten of the bishop, who received the profits of the former. Fulcard held Lanherne, and Godfrey St. Winnow. The services or profits rendered to the bishop in respect of four of the five manors would be comparatively trifling, except on the death of the tenant in demesne and during the minority of his heir. Consequently they are not considered worthy of mention in the _Taxatio_, made by Pope Nicholas IV of the bishop’s temporalities in the year 1291. In order to estimate the extent and value of the bishop’s possessions in Cornwall it will suffice to compare them with those of the clergy, as given in the _Taxatio_ or assessment just mentioned. It must, however, be remembered that Methleigh had ceased to be an episcopal manor before that assessment was made, having been granted by Bishop Robert Warelwast, between 1155 and 1161, to the dean and chapter of Exeter.[63] On the other hand, the manor of Cargol, in Newlyn, had been acquired in the meanwhile.[64] Moreover, Treluswell and Tregella, for civil purposes, had become differentiated into Camwerris (Penwerris), Trevella, Tolverne, Fentongollen, Trevennal, and Trelonk,[65] and for the purpose of ecclesiastical assessment had become known as Tregaher and Penryn.[66] In 1306 Tregaher, or Trocair, was the name of the major portion of the hundred of Powder, and was itself regarded as a hundred. The Bishop’s holdings by military tenure in this hundred were rated at four knights’ fees. Tregaher, the seat of these possessions, which lay east and west of the river Fal, is now known as Tregear in Gerrans. Roughly speaking, the bishop’s manors in this district included the whole of the parishes of Gerrans, St. Gluvias with Falmouth, Budock, Mabe, Mylor, Philleigh, Merther, St. Just-in-Roseland, and Ruan Lanyhorne. His demesne lands were very extensive and valuable, as will be seen by comparing the papal assessment of Tregaher (£20 11s. 5d.) with that of the rectory of Gerrans (£2 6s. 7d.) and the assessment of Penryn (£21 8s. 1d.) with that of the benefice of St. Gluvias (£2).
