Roscrow is the dwelling of Alexander Pendarves, Esq. that married the Lady Dorothy Burke, daughter of the Earl of Clanricarde, and afterwards the daughter of Colonel Granville; his father Carew, his grandfather St. Aubyn, his great-grandfather (Roberts of Truro); viz. Samuel Pendarves, Esq. Sheriff of Cornwall, 19th James I. who gave for his arms, Sable, a falcon rising between three mullets Or; originally descended from the Pendarves of Pendarves, or Constenton, as I am informed. Roscrow gave name and origin to an old family of gentlemen surnamed Roscrow, whose heir, about the time of Richard II. was married to one of the Seneschalls of Holland, where John de Seneschall held by the tenure of knight’s service part of a knight’s fee of land, 3 Henry IV. (See CAREW’S Survey of Cornwall, p. 40.) from whence it appears also that Luke, the son of Bernard Seneschallus, was by letters mandatory, or a mandamus, made one of the Barons of the Exchequer, by King Richard I. (See his arms under GWENDRON.) Innis, Enys, Ennis, is an island or place encircled with water, in this place to be construed as a river island; where two rivers in their confluence meet, and shape the land between them in form of a corner, or triangle; from which place was denominated an old British family of gentlemen now in possession thereof, surnamed Enys; particularly John Enys, Esq. that married the inheritrix of Gregor of Truro, his father Pendarves, his grandfather Winifred, daughter and coheiress of Thomas Price, of Trewardreva; and giveth for his arms, Argent, three water enets Vert, creatures frequently seen in the rivers by which those lands are insulated. A great number of places, or lands, in Cornwall, under the like circumstances, are from thence denominated Enys, Ennis, and Ennys in St. Erme, Roach, Luxsilian, Peransand, taken some times with other words.
