 We first hear of them as hereditary ollamhs to the O'Loghlens of that district, who are of the race of Fergus mac Roigh, of Ulster.The earliest reference to them in print is in the Annals of the Four Masters under the year 1364, where the death of Giolla na Naomh Ó Duibh dá Bhoireann, ollamh of Corcomdhruadh in Brehon law, is recorded.The O'Davoren law school at Cahermacnaghten has been the subject of archaeological and historical interest and its remains are still extant.
