TRILLICK, a market-town, in the parish of KILSKERRY, barony of OMAGH, county of TYRONE, and province of ULSTER, 9 miles (N. by E.) from Enniskillen, on the road to Omagh, to both which places it has a penny post: the population is returned with the parish. It owes its origin to the family of Mervyn, who settled at the neighbouring castle of Mervyn hi the reign of Jas. I., and is a small but very improving town, being a convenient stage from Enniskillen, and having an excellent hotel. The surrounding district is undulating and hilly and is embellished with several lakes: the land in cultivation is generally fertile, and a large tract of waste land has lately been reclaimed. Here is a good market-house, recently repaired by Gen. Mervyn Archdall, of Trillick Lodge, the proprietor of the town and adjacent lands, in which a market is held every Tuesday, chiefly for butter and provisions; and there is a fair on the 14th of every month. This is a constabulary police station; petty sessions are held on alternate Mondays; and courts leet and baron every three weeks, for the recovery of debts under 50s. Here are meeting-houses for Wesleyan and Primitive Methodists, in the former of which also divine service is performed by the clergyman of the Established Church, monthly in winter and once a fortnight in summer. No vestiges are discernible of the abbey said to have been founded here in the 7th century; but near the town are the ruins of Castle Mervyn.
