The Ó h-Anluain (anglicised as O'Hanlon) family was an agnatic extended family comprising one of a string of dynasts along the Ulster-Leinster border. Depending on the advantage to the clan, the Chief of the Name—The O'Hanlon—supported either the Earl of Tyrone or authorities within the English Pale. During the 15th century, ties were close with the famed Earls of Kildare. Frequently, members of the clan would fight on both sides during a rebellion. Some would be outlawed; others pardoned; some ending up on the winning side.
