Sir John Balloch, of Dunnyveg

Sir John "Mor" married Sarah, daughter of Felim O'Neill of Claneboy, by whom he had:
1. John Cathanach.
2. Alastair Carrach, who settled in Ireland, and had a son, Ranald Buy, who had a son, Alexander. This Alexander was knighted for his services against the Irish and Scots by the Earl of Sussex, in 1556, who, at the ceremony, presented him with a gold sword and a pair of silver spurs. He, at the same time, received from the Lord-Deputy a grant of the greater part of the Barony of Dunluce, with the Monastery of Glenarm and the lands belonging thereto.

Through the treachery of Madam of Ardnamurchan, Sir John Mor and his son, John Cathanach, with three sons of the latter, were apprehended, taken to Edinburgh, and hanged on the Borough Muir, an event which, according to the Annals of Loch Ce, took place in 1499.
Though Sir John Mor and his son died on the same day, as the latter had assumed the leadership of the Clan Iain Mhoir in his father's lifetime he may be reckoned as the next in succession.
