O'Neill, while Terence O'Neill, Baron O'Neill of the Maine, Prime Minister of Northern Ireland, was the youngest brother of the third Baron. The family seat is Shane's Castle, near Randalstown, County Antrim where they are involved in the commercial cattle business. O'Neills of the Fews "The Fews" is an area in County Armagh, Northern Ireland, that was a sub-territory under the O'Neills of Tyrone. This O'Neill branch is related to the O'Neill of Tyrone through King Eoghan Mor, circa 1432–1436. The king's younger son Aodh (Hugh) pushed into the territory known as the Fews and founded a lordship there based largely on the unlawful confiscation of considerable amounts of land belonging to the archbishop of Armagh. In the rebellion of 1642, Sir Henry O'Neill, a member of the Fews O'Neills, sided with the English crown while his sons and brothers played a prominent part in the rising. Despite his choice of sides his lands were confiscated and divided among a number of Cromwellian settlers. The chief beneficiary was Thomas Ball, whose grants totalled more than . Sir Henry O'Neill was banished to Connacht, to land in County Mayo, Ireland. Exiled with him was his son Captain Sean/Shane O'Neill. Shane's sons took the surname MacShane, or son of Shane. His grandson William anglicized the name to Johnson. He was a major-general in the American Colonial Army and fought the French at Niagara, New York in French-Indian War. For his significant victory he was granted a baronetcy and made Sir William Johnson, 1st Baronet of New York in 1753. The present holder of that estate is Sir Colpoys Johnson, 8th Baronet of New York. When the Williamite War began in Ireland in 1689, Sir Henry O'Neill's son Turlough was dead and so was Turlough's son Con. The heir to the family's Mayo estate was Con's son Henry, who was a minor and had been sent to France for his education. Despite their non-participation in the war, the O'Neill estates were seized by the Crown. Henry (1676-1745) should subsequently have recovered the confiscated lands; his relatives on the continent feared to send him back to Ireland to stake his claim and the property went by default and was sold in 1702–3. Henry had a heroic career in the French army, rising to become a Lieutenant-Colonel in the Regiment of Clare. He was killed at the Battle of Fontenoy in May 1745, aged 69.
