TREGAYAN, or TREFGAIAN (TREF-GIAN), a parish, partly in the hundred of MENAI partly in the hundred of TYNDAETHWY, and
partly in that of MALLTRAETH, union of ANGLESEY and county of ANGLESEY, NORTH WALES, 2 miles (N. N. W.) from Llangevni;
containing 188 inhabitants. This parish, which derives its name from the dedication of its church to St. Caian, is
situated nearly in the centre of the island, upon the market-road from Llangevni to Llanerchymedd; is bounded by the
parishes of Llangevni, Llanddyvnan, Llanvihangel, Llanbedr-Goch, and Llangwillog; and is computed to contain 2000 acres,
one-half arable, and the rest pasture, with a little woodland. The surface is boldly undulated, and the soil of a light
quality, the principal agricultural produce being oats; and the whole, with -the exception of a small portion, is
inclosed, and under tolerably good cultivation: there is a .mill on a branch of the river Cevni. Tregayan Hall, the teat
of Rear-Admiral Lloyd, is a handsome mansion, pleasantly seated amid some flourishing plantations, and forming a prominent
object in the scenery of the place. The living is annexed to the rectory of Llangevni; and the tithes have been commuted
for a rent-charge of £195. The church is simple and primitive in its construction, with a fine south door and a handsome
east window, and contains eighty sittings, three-fourths of which belong to the tenantry of the soil. The parish register
contains an entry recording the death of William ab Howel, in the year 1587, at the.advanced age of one hundred and five
years; he is said to have been the father of forty-two children, of whom the oldest, at the time of his decease, was
eighty-nine, and the youngest eight years of age. A Sunday school, attended by from 40 to 60 males and females, is
supported by voluntary contributions; and a rent-charge of 2s., bequeathed by John Griffith Lewis, is paid to some
deserving person not receiving parochial relief.
