Part I. Topography of Thomond Chapter 3. Burren, or Corcomroe East

Killonaghan Parish

St. Onchu (in the genitive Onchon), the son of Blathmac, who was venerated at Rathblacmac, in Inchiquin, was the patron of this parish. ^[29] His festival was celebrated here on the 9^th and 14^th of July, according to the authorities cited by Colgan. His church is in good preservation; the door is on the north side. In the townland of Crumlin in this parish stand the remains of a church of greater antiquity, said to have been built by St. Columbkill after he had departed from St. Endeus at Arran. The style of the masonwork marks it as one of the early christian churches. In the townland of Faunarooska, in this parish, the remains of a round castle are found. It is not mentioned in the list of the castles of Clare made about the year 1580. Many cahers exist in the parish.
