The following is taken from Fr. Thomas Walsh's History of the Irish Hierarchy at p. 445:
Aughrim in the barony of Kilconnell and about four miles east of Ballinasloe. An abbey for canons regular of St. Augustine under the invocation of St. Catharine was founded according to some authorities in the 13th century by Theobald, the first butler of Ireland. When the monastery was suppressed its property was granted to Richard, earl of Clanrickard, and his heirs in capite at the yearly rent of £68 9s 6d.
