Trethurffe is an historic estate in the parish of Ladock, near Truro, in Cornwall.
It was held for many generations by the Trethurffe family (originally de Trethurffe) which took its name from the estate. The later descent is given in the Heraldic Visitations of Cornwall as follows: [1]
The Trethurffes' inheritance of part of the Courtenay estates was supposedly foretold by the Courtenay Faggot being "againe sub-divided into other twayne". The Courtenay Faggot was a mysterious naturally mis-shapen piece of wood split at the ends into four sticks, one of which again split into two, supposedly kept as a valued possession by the Courtenay Earls of Devon. It was later interpreted as an omen of the end of the line of Courtenay Earls of Devon via four heiresses. It was seen by the Cornish historian Richard Carew (died 1620) when visiting Hall in the parish of Lanteglos-by-Fowey, Cornwall, then the dower house of Margaret Reskimer, the widow of Sir William Mohun (died 1588), [12] MP, of Hall, the great-grandson of Elizabeth Courtenay, who described it in his Survey of Cornwall as follows: [13]
A farre truer foretoken touching the Earle of Devon's progeny I have seen at this place of Hall, to wit, a kind of faggot, whose age and painting approveth the credited tradition that it was carefully preserved by those noble men. But whether upon that prescience or no, there mine author fails me. This faggot being all one peece of wood, and that naturally growen, is wrapped about the middle part with a bond and parted at the ends into foure sticks, one of which is againe sub-divided into other twayne. And in semblable maner the last Erle's inheritance accrued unto 4 Cornish gent(lemen): Mohun, Trelawny, Arundell of Talverne and Trethurffe. And Trethurffe's portion Courtenay of Ladocke and Vivian do enjoy, as descended from his two daughters and heires.
In 2016 the remnant of the mansion house is a farmhouse with five acres of grounds, operated as a holiday let.[ citation needed ]
