last Viscount O'Neill in 1855, this was the only known surviving branch from Sir Brian McPhelim and still had living members towards the end of the 19th century with Charles Henry O'Neill, a barrister living in Dublin, who was recognised as The O'Neill Clandeboye. The branch of the Clandeboye O'Neills who were Lords of Lower Clandeboye (Edenduffcarrick), successors to Neill McHugh O'Neill, brother of Hugh Oge O'Neill, who ruled Clandeboye north of Kells, generally distinguished themselves by their loyalty to the Tudor and then Stuart Crown in Ireland. Niall O'Neill, the Lord of Lower Clandeboye, had died in 1600 fighting for the Crown during the Nine Years' War against the Earl of Tyrone. In 1626, during the reign of Charles I, his son Niall Oge O'Neill (died 31 March 1628) was the High Sheriff of Antrim. They served the Royalist cause during the Wars of the Three Kingdoms and after showing bravery at the Battle of Edgehill, Niall Oge's son Sir Brian O'Neill was awarded with the Baronetcy of Upper Claneboys. His younger brother, Sir Henry O'Neill, was likewise rewarded with the Baronetcy of Killelagh. The Killelagh O'Neills were Jacobites, loyal to James II during the Williamite War: Sir Neill O'Neill was his Lord Lieutenant of Armagh. They were stripped of their titles because of this and in any case, soon became extinct. Despite also serving James II, their close cousins, the "Upper Claneboys" O'Neills, in the form of Sir Brian O'Neill, managed to survived the Orangist Revolution of 1688 politically unscathed before this line eventually became extinct in the male line by 1799. The Clandeboye O'Neills directly descended from the last sovereign King of Clandeboye, Murtagh Dulenagh O'Neill, continue to exist to this day and claim the title of The O'Neill Clandeboye. After being nudged out of power by junior lines who divided Clandeboye, the senior branch of the family (who retained property in Toome for a time), were implicated in Tyrone's Rebellion, served under Owen Roe O'Neill in his Ulster Army of the Irish Confederate Forces (in the form of Colonel Ever O'Neill) and then Felix O'Neill (died 11 September 1709), his son, served as part of Lord Galmoye Regiment in the Jacobite Irish Army, before prolifically serving in the Irish Brigade of the Royal French Army. Felix's grandson João O'Neill went to Portugal and settled near Almada. His son, Carlos O'Neill, was a Professed Knight of the
