Not ruined, not buried under a later village, simply gone, its precise location unresolved. What survives are the traces that tend to outlast everything else: a motte and a parish church, both of which hint at where the settlement's centre of gravity once lay. A motte, for those unfamiliar with the term, is an earthen mound built to carry a timber or stone fortification, typically the focal point of a Norman manorial estate.

The documentary record, however sparse, gives Killamery a surprisingly legible history. The Earls Marshal acquired the townland around the beginning of the thirteenth century and granted it as a feudal tenancy to the Tobins, also known as De St. Albin, who were lords of Kaemshinagh. By 30th April 1247, a Thomas de St. Albin held it from Richard de Clare, Earl of Gloucester and Hertford. The settlement remained significant enough to appear in the Calendar of Ormond Deeds on more than one occasion: around 1399 the Crown was owed half a knight's fee from Killamery, and by around 1413 royal service from the place was assessed at twenty shillings. As late as 1584, a Walter McRichard Tobin of Killamery was named in connection with land grants. The family's long tenure came to an abrupt end when James Tobin forfeited the land following the 1641 Rising, one of countless confiscations that reshaped landownership across Ireland in the mid-seventeenth century. After that, Killamery disappears from the record as any kind of functioning settlement, and the community that once owed fees to a king and gave its name to a feudal grant quietly ceased to exist.
