The following description is quoted from [Tonkin 1739] and must be read in the context of that date. The extract is taken from [Polsue 1868]. Other extracts are available online.
Morva, is situated in the hundred of Penwith, and is bounded to the west by S. Just, to the north by the sea, to the east by Zennor, to the south by Sancred and Maddern. It is a daughter church to Maddarne, the vicar of which performs divine service, and preacheth in the morning on the first Sunday in every month. The said vicar hath the small tithes.
Morva signifies Locus Maritimus, a place near the sea, as this parish is. The name is sometimes written Morveth, implying much the same sense.
The chief place, and almost the only one of note in this little parish, is Tregamynyon, that is, the stony dwelling, which was for several generations in the family of Lanyon, and the residence of a younger branch thereof ever since the 30th of Queen Elizabeth; for in Trinity term the 31st year of her reign was a fine passed at Westminster between William Lanyon, gent. and Richard Lanyon, Esq. and John Lunyon, gent., of three messuages, ten acres of meadow, sixty acres of pasture, one hundred and fifty acres of furze, one water-mill, &c., in Tregamynyon. Here his posterity flourished in good repute till the reign of Queen Anne, when John Lanyon, of this place, gent. and John Lanyon jun. his son and heir, joined in the sale of this estate to John Borlase of Pendeen, Esq., who is. the present possessor thereof. The said John Lanyon, jun., married to his wife Frances Brydges, sister to James Lord Chandos, and aunt to the Duke of that name, who is since dead without issue, being well stricken in years when he married, and twice a widower before. John Lanyon, the father, married Borlase of Pendeen. His grandfather was commonly called the Golden Lanyon, as having gotten great riches by tin, which he divided among his numerous issue; but before I quit this place I must relate for the benefit of my readers what Mr, Lanyon, sen. told me respecting the covering of his house, as it may be of great use to persons building in high and exposed places. That not being able to keep his house here in good repair, it being rifled and uncovered by every storm, he at last resolved to plaster it with lime and hair on the lathes within, where the stones are fastened; after which he had not the least stripping of his healing for thirty years. This same thing was tried with the same success by Mr. Hector Trelevan, of S. Agnes; and it is, I verily believe, a certain and cheap prevention of damage.
The manor of Carvolghe, or Corvaeghe.—This manor was one of those forfeited by Francis, Tregian, Esq.
It appears by [ua]n inquisition taken in the
fifth year of King Charles the First, that the manor then
belonged to Ezekiel Grosse, of Camborne, gent.
