The etymology of this name, Boyeton, may be either from the Cornish
word “byu,” which is pronounced like “boy,” or from the French “bois,”
a wood, which agrees extremely well with its situation in the midst of
woods.
I take most if not all the parish to be a part of or holden from the
manor of Boyton, which belonged to the Priory of Launceston, and was
ultimately given, inter alia, by King Henry the Eighth, to the Duchy
of Cornwall, in exchange for the honour of Wallingford.
