Murtagh Dulenaach O'Neill was the last to claim overlordship of all Clandeboye. During his reign the sons of Phelim Bacagh and Niall Oge founded their own lordships at Murtagh's expense, reducing him to lord in name only. The Annals of the Four Masters regarded Hugh, son of Niall Oge, as lord of Clandeboye until his death in 1555.

The lordship of Lower Clandeboye (also known as Northern Clandeboye) was founded by the sons of Phelim Bacagh O'Neill. This covered the north of what is today County Down.
