What survives is essentially a name, a general location in the north portion of the townland of Kilmaniheen West, and a cluster of documentary references pointing back through centuries to something that once mattered considerably in this corner of the diocese of Ardfert.

The place-name itself carries the earliest clue. Kilmaniheen derives from the Irish Cill Mhainchín, meaning the church of St Munchin, and according to local tradition the original foundation was made by Bishop Domaingen in 630 AD. By the medieval period the site had accumulated institutional weight: a papal taxation list compiled between 1302 and 1307 valued the church of Kylmoginan, as it was then recorded, at six shillings and eightpence within the Deanery of Hacudeo. By 1398 the Augustinian prior and convent of St Mary's Killaha held an appropriation of the vicarage, meaning that the revenues of the parish living had been formally assigned to that religious house, a common enough arrangement in late medieval Ireland. What is less clear is where exactly the early church stood. The graveyard annotated on the 1841 Ordnance Survey six-inch map may have occupied the site of a medieval predecessor, but even that cannot be confirmed. A structure labelled as a church on the same edition was described by the rector himself as having served only as a school and mission house, never as a place of worship. A separate Church of Ireland building, with seating for roughly 120, appeared to the east by the time of the second Ordnance Survey edition, and was under the care of the Reverend Edward Norman in the 1850s and a Reverend O'Connor in the 1890s.

What the record leaves behind, then, is a layered absence: a graveyard documented once and then dropped from subsequent mapping, built over before anyone thought to preserve it, attached to a church whose precise medieval location remains unknown, and serving a community whose burial ground has left no physical mark on the landscape.
