John, the second son, became a colonel in the army, commanded the militia of Cornish Miners, served in parliament for the borough of Saltash, and four times for Truro. He died unmarried in 1814, at Polvellan, a place that he had created with great taste on the southern side of the lake, loch, or loo, formed by the two rivers above East and West Looe, and close on the margin of a large salt water pond, made to retain the sea water at high tide, afterwards to give motion to the machinery of grist mills, from whence Mr. Lemon named his new place Pol-Vellan, in Cornish the mill-pool. Colonel Lemon was such a proficient in music as to perform extemporaneous voluntaries; and several psalm tunes and chants of his composition have been printed. Anna Lemon, the sister, married Mr. John Buller, of Morval. Sir William Lemon greatly improved Carclew, and added most materially to the extent of the property round his seat, by purchasing from Mr. Trefusis the manor of Restronget, which had been acquired some years before from Mr. Trevanion. He is most worthily succeeded by his son Sir Charles Lemon, now member for the county, to whom the house at Carclew is indebted for still further improvements made in the best taste; the grounds and gardens have also been enlarged and beautified, and further arrangements and other decorations are still in progress. It is a very curious circumstance that several acres of ground at Carclew have been recently found covered with the _eria ciliaris_, not known before as an English plant. Of his eight sisters three have married Cornish gentlemen. Harriet, married to the late Lord de Dunstanville. Caroline, to John Heale Tremayne, esq. late member for the county. Jane, to her double cousin-german Mr. Anthony Buller, Barrister-at-law, and knighted on his going to India as a judge. The family of Trefusis can now scarcely be considered as connected with Cornwall, Robert George William Trefusis having succeeded, on the death of George Walpole, Earl of Orford, to the barony in fee of Clinton, created by writ of summons in the year 1299, the 28th of Edward the First, and under a deed of settlement, made by the same Lord Orford, having succeeded also to a very large estate, chiefly in Devonshire; and finally, in consequence of their having alienated by far the greater part of their possessions in this county. This gentleman having married Marianne Gaulis, a lady of Switzerland, and died in 1797, has been succeeded by his son Robert Cotton St. John Trefusis. He married one of the daughters of William Stephen Poyntz, Esq. and niece of Mark Anthony Browne, last Lord Montague, of Cowdray Castle, in Sussex; but having died without issue, he is succeeded by his brother Charles Trefusis. The widow is recently married again to Colonel Horace Seymour. The situation of Trefusis is very beautiful, the whole jutting into Falmouth harbour, with Penryn river on the south and Milor river to the north.
