Trevannence I believe to mean the town in a valley of springs. This barton has belonged to my family upwards of five hundred years, so that we have used the name de Trevannence, by customary inheritance of the manor of Tywarnhails. But in 1559 Henry Earl of Rutland, then Lord of the Manor, sold the fee of his right in Trevannence to Richard Carne the younger, of Camborne, Gent. who reconveyed it the same year to John Jeffry; and he conveyed it, in 1593, to Thomas Tonkin. [This estate was the property and the seat of Thomas Tonkin, of Trevaunance, Esq. who made large collections for a parochial History of Cornwall. Mr. Tonkin enjoyed his estate but a few years; he died in 1742. His two sons, who did not long survive him, successively inherited his estates, which, after their death, were for a while in the possession of Thomas Heyes, Esq. who married the daughter and heir of his son James, but left no issue; the only child of his daughter, who married Foss, having died unmarried, they descended to the representatives of the three daughters of Thomas Tonkin, who died in 1672; which daughters had married into the families of Jago, Cornish, and Ley. Mr. John Jago, and Mr. Hugh Ley, the immediate descendants of two of the daughters, are now possessed of two thirds of the manor of Trevaunance, and of such portion of the manor of Lambourn as extends into this parish, and was part of the Tonkin estate (except some lands sold to J. Thomas, Esq. of Chiverton). The other third part has been subdivided. Mr. Thomas has one half of it by purchase, the other is divided between Mr. Geach, a descendant of the family of Cornish, and Mr. Paul Clerk.[7] Trevaunance House was taken down a few years after the death of Mr. Tonkin; there is now a cottage on its site. _Lysons._] The above-named Richard Carne gave for his arms (as appears by his seal) a pelican in her nest, with wings displayed, feeding her young ones, which coat is still to be seen in Trevannence seats, and in the roof of St. Agnes’ church. He was descended from the Carnes of Glamorganshire, in Wales, who derive their pedigree from Ithal, King of Gwent, whose direct ancestor was Belimaur, the father of Cassibelan; which Carne settled in Cornwall, as we have it by tradition, upon his ancestor’s marriage with the heiress of Tresilian, of Tresilian in the parish of Newlyn. Westward of Breanis riseth with a gentle ascent the great hill commonly called St. Agnes’ Beacon; formerly Carne Breanic. On the top are three stone barrows; to the westward of the one now used for a beacon, are visible remains of a small square fortification.
