Killeen

From Thomas Walsh's History of the Irish Hierarchy:

Killeen in the barony of Skrine two miles south of Tarah gives a title to the family of Fingal Near the castle which De Lacie built AD 1180 was a church dedicated to the Virgin Mary beautifully carved and in the pointed style The east window was large and of considerable height and west of the church were two towers The ruins of many ancient tombs are still to be seen with several figures in the episcopal habit and mitres on their heads This is supposed to be the Killeen in which seven bishops are interred
