Those lands of Trenwith were of old pertaining to the Earls or Kings of Cornwall, afterwards to the Kings of England; and were held by the tenure of knight service by such as possessed them, if not from King Arthur’s days, (see Dundagall) yet from William the Conqueror’s, who, in imitation of him, gave bartons, manors, fields, large territories of land to his favourites, under the tenures of villeinage and knight service in capite, by means of which knight service those tenants were obliged to do him any necessary service, either in wars or to his royal person, for the performing whereof he took their oaths in public courts, both of homage and fealty; and by reason of this tenure he disposed of the bodies of their heirs in marriage as he listed, and retained in his custody and wardship their whole inheritance till they accomplished the age of twenty-one years; and by those examples other men of great possessions did the like. Those lands of Trenwith, tempore Henry IV. were held by that tenure in capite by Edmund Plantagenet, alias Beaufort, Marquess of Dorset, grandchild to John Duke of Lancaster, 21 Henry VI. 1442, consisting of four knights’ fees, 3 Henry IV. (See Carew’s Survey of Cornwall, p. 39). He was slain at the battle of St. Alban’s 1450, on the part of Henry VI. against Richard Duke of York; as also was his son Henry on the same part after the battle of Hexham, and his brother Edmund after Tewkesbury 1471, beheaded by King Edward IV. and his whole estate confiscated to the Crown; from whence Bayliff, now Trenwith, purchased part of those lands, which still pays high rent to the Kings of England. In like manner Humphrey Plantagenet, fourth son of King Henry IV. held by the same tenure in Conerton, Binerton, Drineck, and Ludgian, four knight’s fees of land in those places. He was impeached of treason at the Parliament held at St. Edmund’s Bury in Suffolk; afterwards murdered; and those and all other his lands confiscated. TONKIN.

The sheaf in possession of Edward Noseworthy, Esq. The town of St. Ives, in Mr. Carew’s days, was of small value or consequence for wealth, buildings, or inhabitants; although it now be much altered in these particulars, and equals several other fellow corporations. Of old it hath been privileged by the Earls of Cornwall with the jurisdiction of a Court Leet, and with sending two Members to Parliament; also with fairs and a weekly market. On the island (or peninsula) north of St. Ives, standeth the ruins of an old chapel, wherein God was duly worshipped by our ancestors the Britons, before the church of St. Ives was erected or endowed; betwixt which island and the shore is an indifferent roadstead with some winds for ships to lie at anchor.
