Origin of name
The origin of the name, as in most place names in Ireland, is a description of some geographical feature, Lucia means rushy place, as can be seen, by the river which shelters the place. The place most likely began as a hermitage in times soon after St. Patrick. Local tradition claims that there was a monastic settlement in the field between Cordrehid Road and the graveyard road and a round tower located somewhere on the boundary within Stephen Murray's land.
Killukin, which derives from Cillibhicin in Irish and pronounced Kill-Evickeen. The saint seems to be the person whom the catalogue of the churches of the Diocese of Elphin calls Lunecharia and asserts to be venerated on 7 June in a certain chapel of the same diocese called Kill Lunechair which lies near the Episcopal See.
