In 1883, Rev. M. Comerford, visited the site and reported that " An old church, in ruins, stands here in an extensive grave-yard; portion of the four walls remain, and show it to have been very small and very ancient; it measures about 40 feet in length, by 16 feet in width; there is a window in the west gable, 3 1/2 feet in height and only four inches wide; another window, still smaller, appears in the Epistle side of the altar place"
