Saint MaCartan’s was the first church in Tievenadarragh townland, where the three roads meet ( locally called The Stick) , was built in 1740 by Dr. Theophilus MacCartan to replace the ancient church on the island at Loughinisland, which was dismantled by the Forde family in 1720. In the autumn of 1787, Father Patrick McCartan built a new church for the parish of Loughinisland and dedicated it to S
t. Macartan, patron saint of the diocese of Clogher. Its opening presaged the end of acute sectarian animosity and though the penal legislation was still on the statute books, priests carried out their duties openly, but prudently, in most places. So long as Catholics gave no other cause of offence than the unobtrusive practice of their faith, the authorities from then on were prepared to tolerate them. The church took two years to build and the inscription stone in Latin set into the wall above the sacristy door is translated: " This Church built by the donations of the faithful and by our own industry was dedicated to the Lord of all Creation A.D. 1787". The Ordnance Survey Memoirs of 1836 describe the church as being 80 feet by 58 feet in a T shape. It was capable of holding 612 people and the floor was paved with stone after the manner of a road and the whole concern is in good repair. The Census of 1861 says that there were 2,700 Catholics in the parish. The parish priest 1847-1860 was Rev. James Crickard 1866 -1906.
