ST. ERVAN, ST. ERUM, ALIAS ERBYN.
HALS.
Is situate in the hundred of Pyder, and hath upon the north St. Merryan; east, Little Pedrick; west, St. Evall and Mawgan; south, St. Colomb. For the modern name, if it be not taken up in memory of Gerint ab Erbin, one of King Arthur's admirals at sea, slain by the Saxons at London, (see Dundagell,) the same is derived from the divine service or worship of God performed in this church, for Ervan, Ervyn, in the British tongue signifies a humble request or supplication, and properly signifies at the holy Litany, as Litania in Latin. In the Domesday Book or Roll, 1087, this district was taxed under the jurisdiction of Trewinock, now Trewinicke, that is, the beloved lake, or spring of waters, running to the sea; still the voke lands of a manor. In the Inquisition of the Bishops of Lincoln and Winchester, 1294, Ecclesia Sancti Ervanis, in Decanatu de Bolton, was valued at cs. In Wolsey's Inquisition, 1521, it was rated 19l. 6s. 8d.; the patronage formerly in the Prior of Bodmin, who endowed it, now Morice. The incumbent Vivian, and the parish rated to the 4s. per pound Land Tax, 1696, 100l. 8s.
