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

St. Manchín, who was also the patron of the diocese of Limerick, was the saint to whom this parish was dedicated. He was contemporary with St. Ailbhe of Emly, St. Luchtigern of Tomfinloe, St. MacCreiche of Kilmacrehy, and St. Flannan of Killaloe. The church of Kilmanaheen was placed on the summit of a hill in the townland of Lissatunna, but scarcely any remains of it now exist; the burial-ground attached to it is in much use. Previously to the building of the church, the Dún, or residence of Baoth Bronach king of Corcomroe, had stood on the same spot, but he resigned the place to St. Manchín for the glory of God.^[46] Three burial grounds for children are noticed in the parish of Kilmanaheen, namely, Kilcornan, Calluragh, and Kyleduff. A castle once stood at Ennistymon, but no trace of it remains to our time. It belonged in 1580 to O’Connor.
