CEIRCHIOG, a parish in the hundred of LLYVON, county of ANGLESEY, NORTH WALES, 4 miles (S. E.) from Bodedern, containing 168 inhabitants. The name of this parish is descriptive of the produce of the soil, which is well adapted to the culture of oats, of which great quantities are grown in the parish and in the adjacent district. The living is a perpetual curacy, annexed to the rectory of Llanbeulan, in the archdeaconry of Anglesey, and diocese of Bangor. The church, dedicated to the Holy Rood, is a small neat edifice, situated on an eminence in a large field on the south side of the road from London to Holyhead. A rent-charge of £2. 10. was bequeathed by Sergeant Wynn, for the benefit of the poor of this parish. The average annual expenditure for the support of the poor is £74. 6.
