Fate of Clandeboye
O'Neill family tree showing descent of Viscount O'Neills from Brian McPhelim. Despite Sir Brian McPhelim's attempts to thwart English settlement of his lands, the son of Neill McBrian Fertagh, Con, who succeeded his father as lord of Upper Clandeboye, made a deal with Hugh Montgomery and James Hamilton that resulted in the three-fold division of the lands comprising his estate in 1605. He sold off the rest and died in 1619. Their subsequent plantations expanded rapidly. The scheme for settling County Antrim, including the territory of Lower Clandeboye, passed from Essex to Sir Arthur Chichester, who was more successful than his predecessor.
