This parish is a rectory. The vicarage is valued in the King’s Book at 8_l._ 0_s._ 11_d._ The rectory is a sinecure, and the rector presents to the vicarage. Trenant was sold by Mr. Medhope in the 1st year of Queen Anne to Edward Dennis, of Liskeard, attorney-at-law, who had before a mortgage on it, and it is now the seat of his son, George Dennis, Esq. sheriff of Cornwall in the 1st year of George II. In respect to the name of this parish, I cannot agree with Mr. Hals in supposing it God’s Lake. I rather interpret it the Black Lake, alluding to the river Looe, which runs through it, and I guess takes that name from its forming a deep lake or pool between the two towns and it when the tide is in. THE EDITOR. The etymology of Dulo given by Mr. Tonkin appears to be very probable; but another is quoted by Mr. Bond, in his excellent work, entitled, “Topographical and Historical Sketches of the Boroughs of East and West Looe, in Cornwall,” printed by Nichols in 1828, p. 48: “In Archbishop Usher’s work, Britannicarum Ecclesiarum Antiquitates et Primordia, it appears that the church of St. Theliaus, in Wales, is called, Lhan Deilo Vaur, the Church of Great Theliaus; and the change of Deilo to Dulo is so easy, says a recent writer, that St. Theliaus seems to have the best title to this parish, as patron and owner of it. In confirmation of this conjecture, says the same writer, we find in the barton of Treridern in St. Burian a chapel dedicated to St. Dillo, who is indisputably the Theliaus.” St. Theliau, or Theliauses, was born at Ecclesis Gwenwau, near Monmouth. He is said to have made a pilgrimage to Jerusalem about the year 500, with St. David and St. Paternus. On his return he became Bishop of Landaff, and he has ever since been considered as the patron of that diocese. Trewargy, properly Tre-war-gie, the house or town on a stream, is now the property of Mr. Eliot, a gentleman resident in London. Trenant has frequently changed its proprietors since the time of Mr. Hals. It passed from Mr. Dennis to his sister’s son, Sir Christopher Treise, who was Sheriff of Cornwall at the accession of King George the Third, and knighted on the occasion of presenting an address. The property thus devolved on his nephew Sir John Morshead, of Cartuther, who acquired a large fortune by his marriage, succeeded to an ample patrimony, dissipated the whole, and left the prefix of three letters as an inheritance to his son. It was then purchased by Admiral Sir Edward Buller, and again disposed of after his decease to Mr. Hope, who at this instant, 1833, offers it for sale. Some at least of these changes have been ascribed to combinations and arrangements which were materially varied in the last year.
