One of the heirs general to the Ormond inheritance was Thomas Boleyn, whose mother was a Butler. Boleyn was the father of Anne, whose star was rising at the court of
King Henry VIII of England. As the king wanted the titles of Ormond and Wiltshire for Thomas Boleyn, he induced Piers Butler's father and his coheirs to resign their claims on 18 February 1528. Aided by the king's Chancellor, Cardinal
Thomas Wolsey, Butler was granted the earldom of Ossory instead. Butler was created, in 1535, Viscount Thurles. In 1537, Thomas Boleyn, Earl of Ormond died without a son, whereupon the King on 22 February 1538, restored the earldom of Ormond to Butler's father. Viscount Thurles's father died on 26 August 1539 and was buried in
St Canice's Cathedral, Kilkenny. Thurles succeeded as the 9th Earl of Ormond and was confirmed by
Act of Parliament, 6 November 1541, in the
Earldom of Ormond, with the pre-eminence of the original earls.
Cokayne, in his
Complete Peerage numbers him the 10th Earl of Ormond because he counts Thomas Boleyn as the 9th. In the early 1540s, Lord Ormond, as he now was, gradually restored the Butler dynasty to their former position of influence, leading to antagonism from the quarrelsome
Lord Deputy of Ireland, Sir
Anthony St Leger. St Leger gave Ormond command of the Irish forces in the Anglo-Scottish War of 1544. On the face of it, this was an honour, but allies of Ormond accused St Leger of deliberately sending Ormond into danger. Ormond himself demanded an inquiry into claims that St Leger had planned his murder, and the matter was thought to merit a
Privy Council investigation; the Council found in favour of St Leger and he and Ormond were ordered to work together amicably in future. Key allies of Ormond like
John Alan and
Walter Cowley were removed from office, and Ormond was struggling to maintain his standing when he was poisoned. == Poisoning and timeline ==
