In the Domesday Book this district was taxed by the name of Trevoes or Trevose, id est, the maid or virgin’s town; then and now the voke lands of a manor annexed to Pawton, or Polton, (parcel of the lands of the Prior of Bodman and Bishop of Exon before the Norman Conquest,) on the confines of which, towards the sea, is yet extant the ruins of an old church, chapel, and cemetery pertaining thereto, dedicated to St. Constantine, the first Christian Emperor of Rome: which, upon the encroachment of the sea-sand on the marsh beneath, which surrounded and overwhelmed the same, was discontinued, and thereby gave occasion to the inhabitants to build their now church of Merin in a more secure place, further up in the country from the sea and sand, and moor or marsh ground; the church of St. Constantine being in part converted now to a dwelling house for poor people. Near this church is yet extant St. Constantine’s Well, strong built of stone and arched over; on the inner part hereof are places or seats for people to sit and wash themselves in the streams thereof; the consequence of which facts, if the inhabitants may be credited, is not only very refreshing and salubrious, but, if it be dry weather, immediately showers of rain will follow. The barton of Trevose is now, by lease, in possession of Gregory Peter, Esq. and Lawrence Growden, that well-known Quaker, the reversionary fee pertaining to Sir Nicholas Morice, Baronet, as parcel of his manor of Pawton; and is a large lofty promontory of land, shooting out far into the Irish sea, beyond all other lands there, yet notable for its production of sheep, barley, and rabbits, and not altogether unprofitable for bullocks in winter season; and as fatal and unfortunate for wrecking ships, that happen by night or stormy weather to fall on the rocks thereof, at that or any other time. Arel-yn, alias Har-lyn, in this parish. This barton is the dwelling of my very kind friend and brother-in-law, Gregory Peter, Esq. Sheriff of Cornwall part of the last year of William III. and first of Queen Anne, 1701; he married Elizabeth, daughter of Gove of Devon, the relict of William Wadland, merchant, by whom he had issue two sons, William and John; William died without issue, and John that married Anne, the daughter of Sir John Coryton, of Newton, Baronet, by whom he hath a numerous issue of children of both sexes. After the death of the said Elizabeth, he married the daughter of Anthony Carveth, of Peransand, Gent. his cousin-german removed, and hath issue by her Francis Peter. Gregory Peter aforesaid was the son of Thomas Peter, of Treater, in Padstow, Gent. who married the daughter and heir of Mitchell, lord of Harlyn; the which Thomas Peter was the son of John Peter, of Trenaran, in Padstow, Gent. that married Toms, as John Peter was the son of John Peter of Trenaran, that married Kestell.
