He was born at Tottenham, Middlesex, 27 September 1678, and was younger brother of Benjamin Hoadly. He was a member of Saint Catharine"s Hall, Cambridge (Bachelor 1697), and in September 1700 was appointed under-master of the of Norwich grammar school, of which his father was head-master.
He served as Bishop of Ferns and Leighlin from 1727 to 1730 and as Archbishop of Dublin from 1730 to 1742 and Archbishop of Armagh from 1742 until his death. After passing some years there he became chaplain to Bishop Gilbert Burnet, who gave him the rectory of Saint Edmund"s, Salisbury, and made him successively prebendary (21 February 1705-1706), archdeacon (6 November 1710), and chancellor (16 April 1713) of Salisbury. The author of a pamphlet The Salisbury Quarrel Ended of 1710, relating to local conflicts, attributed to Hoadly"s influence the High Church party"s troubles with Burnet.
In 1717 Lord King, as chief justice of the common pleas, presented Hoadly to the rectory of Ockham, Surrey.
And in 1727 he was consecrated bishop of Leighlin and Ferns. William Whiston protested because he thought Hoadly ignorant.
In July 1729 a vacancy occurred in the archbishopric of Dublin, Hugh Boulter wrote to Sir Robert Walpole in support. And Hoadly was translated to Dublin in January 1730.
As archbishop of Dublin he built the residence of Tallaght at a cost of £2,500.
In October 1742 Hoadly became archbishop of Armagh on Boulter"s death, the lord-lieutenant, the Duke of Devonshire, who was at court when the news arrived, telling the king that he could not do without him. As primate he consented to the abolition of restrictions on Roman Catholic services. He was for many years a major force in Irish politics.
Hoadly died at Rathfarnham, 19 July 1746, of a fever.
Hoadly"s only daughter, Sarah, married on 29 November 1740 Bellingham Boyle (b 1709), Member of Parliament for Bandon Bridge, a distant cousin of the Irish Speaker Henry Boyle.
