The History and Topography of the County of Clare by James Frost: Chapter 7

In the Martyrology of Donegal, under the date of the 21^st of September, is found the following entry:—“Saran, son of Tighernach, son of Maenach of Lesan, in Sliabh Callann, and of Cluain-da-acra, in Cehair.” O’Curry was of opinion that this Cluain-da-acra might be the Clooney of Corcomroe.^[44] The church is much ruined by time. At a little distance is a holy well dedicated to St. Flannan, where rounds are yet made. In a townland of the parish, called Killeighnagh is a small burial-ground, and in another place named Mooghna, is noticed a little grave-yard and well styled Tobar Mooghna, used by persons suffering from sore eyes. The castle of Glen, now well nigh ruined, stands in this parish. Sir Daniel O’Brien was the proprietor of it in 1580.
