Pery is born into one of Limerick’s most politically influential families, elder son of the Rev. Stackpole Pery and Jane Twigge. His maternal grandfather is William Twigg, Archdeacon of Limerick.
A trained barrister, Pery becomes a member of the Irish House of Commons for the Wicklow Borough constituency in 1751. On the dissolution of the house following the death of George II, he is elected for the constituency of Limerick City and serves from 1761 until 1785, becoming Speaker of the House in 1771. In 1783, he stands also for Dungannon, however chooses to sit for Limerick City. He is considered one of the most powerful politicians in Ireland in his time, leading a faction which includes his nephew, the future Earl of Limerick, and his relatives by marriage, the Hartstonges. Following his resignation, he is created Viscount Pery, of Newtown Pery, near the City of Limerick, in the Peerage of Ireland, entitling him to a seat in the Irish House of Lords. As he has no male heirs, his title becomes extinct on his death on February 24, 1806.
Pery is also noted for his part in the history of the architecture of Limerick. In 1765, he commissions the engineer Davis Ducart to design a town plan for land that he owns on the southern edge of the existing city, which leads to the construction of the Georgian area of the city later known as Newtown Pery. He is also commemorated in the naming of Pery Square.
Pery marries Patricia (Patty) Martin of Dublin in 1756, who dies a year later, and secondly Elizabeth Vesey, daughter of John Vesey, 1st Baron Knapton, and Elizabeth Brownlow. He and Elizabeth have two daughters:
- Hon. Diana Pery, who marries her cousin Thomas Knox, 1st Earl of Ranfurly
- Hon. Frances Pery, who marries Nicolson Calvert, MP for the borough of Hertford
Pery’s younger brother, William, is a leading figure in the Church of Ireland, becoming Bishop of Killala and Achonry and subsequently Bishop of Limerick, Ardfert and Aghadoe, and also ennobled as Baron Glentworth. William’s son, Edmund, is made Earl of Limerick in 1803 as a result of his support for the Act of Union. Pery’s younger sister is Lucy Hartstonge, the founder of what is now St. John’s Hospital, Limerick.
