The next name—Trevelaboth—presents no difficulty. There is a continuous chain of evidence to show that it is identical with Traboe, a small manor in the parish of St. Keverne. In order to equate the three holdings which remain, viz. Lismanoch, Trequaners and Carmailoc, it will be necessary to refer to a document in the Otterton custumal[129] in which they appear as Tremain, Listyavehet, Treganeis and Carmaheleck. Carmailoc is obviously Carmaheleck or Carvallack, a holding in St. Martin’s parish which derives its name from the prehistoric earthwork in that parish. If we suppose the “n” in Trequaners and Treganeis to be a false reading for “u”—a pardonable blunder of constant occurrence—we have the modern tenement of Tregevas or Tregevis also in St. Martin’s. We are thus left with Lismanoch as the equivalent of Tremain (the modern Tremayne) and Listyavehet. Tremain calls for no remark in this connection: everyone knows where it is. Lismanoch, of which it appears to have formed a portion, presents some difficulty, because in that form the name is now unknown. As Lesmanaoc it occurs in a grant of King Edgar in 967 to Wulfnod Rumancant. In that grant its boundaries are minutely described, but unfortunately to little purpose owing to the fact that many of the place-names in it are either purely descriptive or have become so altered during the ten centuries which have elapsed since the grant was made as to be incapable of recognition. One or two points are clear. Lesmanaoc was of considerable extent. For some distance it lay along the river which empties itself at Porthallow. It must have reached well towards the south of St. Keverne parish if “Castell Merit” and “Crouswrah” (two places mentioned in the charter) are, as seems probable, the modern tenement of Kestlemerris and Crousa Downs. At the time of Count Robert’s charter its area had evidently been contracted, otherwise it could hardly have escaped mention in Domesday Book. The portion which had been lost was probably the southern portion, for no mention is made of any possessions south of Traboe in the grants of the priory lands after its dissolution. These considerations lend support to what is something more than a conjecture of Mr. Henry Jenner, viz. that in the two tenements now known as Lesneage we have the site of Lesmanaoc. Lesneage, as he points out, may well be a contracted form of Lesmeneage, which in turn may be only another form of Lesmanaoc, on the same principle as Treveneage in St. Hilary can be shown by an unbroken series of documents to have been derived from Trevanaek. It is worthy of remark that within a short distance of Lesneage is Mill Mehal or St. Michael’s Mill. If this be the true etymology then the name Listyavehet becomes less formidable than it looks.
