The medieval church ruins and graveyard of Kilfinane are in the townland of Kilfinane, in the parish of Kilfinane and in the barony of Coshlea. It is located on the northeast edge of Kilfinane town, on Castle St., with Kilfinane Castle to the west.
The name Kilfinane in Irish is Cill Fhionain, meaning the church of Fionain (Logainm.ie). The early English records call it Keilfinny or Keilfinane, and imply an earlier form, Coill Finghin, Finghin’s Wood (not cil or ‘church’). It's quite possible that there may have been a Drum-, Coill-, and a Cil Finghin here.
