http://www.genuki.org.uk/big/eng/Cornwall/MawganinMeneage/The parish of Mawgan-in-Meneage is situated in the deanery and Hundred of Kerrier, and is so denominated to distinguish it from Mawgan-in-Pydar Hundred. It is bounded on the north by Wendron and the Helford estuary which separates it from Constantine, on the east by St Martin-in-Meneage, on the south by Cury and on the west by Gunwalloe.
St Meugan was venerated in south-west Wales and also in Brittany, where he was known as Maugan or Mogan. Meneage is believed to be a derivation of 'monk'. Mawgan is an Attractive village in south-west Cornwall between the Helford River and Gunwalloe. There are memorials in the church to the influential Vyvyan family.
"Three noble Cornish families, the Roskymers, Carminowes, and Vyvyans, were once settled in this parish. Onlt the latter remains (1894). Their seat is a fine old castellated building with a chapel, called Trelowarren. The family of Vyvyan dates from the time of Edward VI. In the civil wars they attached themselves with the most devoted loyalty to the royal cause, and suffered severely from the Parliamentary forces. In testimony to the eminent services of Sir Rd. Vyvyan, then the head of the family, there hangs in there house a large painting, by Vandyke, of King Charles I on horseback, presented to the family by Charles II. Another Sir Richard Vyvyan, a lineal descendent of this brave old cavalier, was imprisoned in the tower by George I, on suspicion of being concerned in favouring the design of the Pretender. Still another Sir Richard Vyvyan died at Trelowarren on August 15th, 1879. He was a Tory of the old school, and represented Bristol in Parliament after the passage of the Reform Bill in 1832 until the dissolution of 1837. In 1841 he was returned as Member for Helston, which borough he continued to represent up to 1857, when he finally retired from public life.
At Mawgan Cross, in this parish, is a very old stone, with an inscription in Cornish, which has been thus interpreted "What lieth here is not the soul." At Gear, Gweek Wood and Carvallock, are remains of extensive earthworks. On Goonhilly Downs, which extends into this parish, are many barrows, in which have been found coins and weapons of war. A "fogou" or cave exists at Trelowarren near the entrance to an ancient entrenchment, the remains of which can still be traced. This parish was well wooded, and the walks and drives along and about the Helford River are scarely to be equalled for variety and picturesque beauty in the county. Numerous Roman coins have from time to time been found in this parish."
The Churchtown is the chief village of the parish.
