This was an O'Brien home from at least the late 18th century. In 1837 Lewis described Columbkill Cottage as the "neat residence" of Terence O'Brien esq. Griffith's Valuation records Mary Anne O'Brien (the widow of Terence) as the occupier holding the property from John Kirwan. The buildings were valued at over £10. In the 1870s Morty O'Brien of Glencolumbkille owned 396 acres in county Clare. This is house is no longer extant.
