Justice of the Peace in the context of "Hugh Grosvenor, 1st Duke of Westminster"

Sir John Gray JP (13 July 1815 – 9 April 1875), sometimes spelt John Grey, was an Irish physician, surgeon, newspaper proprietor, journalist and politician. Gray was active both in municipal and national government for much of his life, and had nationalist ideals – which he expressed as owner of the Freeman's Journal, chairman of the Dublin Corporation Water Works Committee between 1863 and 1875, and Member of Parliament in the House of Commons of the United Kingdom of Great Britain and Ireland for Kilkenny city from 1865 until his death. He was a supporter of Daniel O'Connell, and later of Charles Stewart Parnell, and advocated a repeal of the Act of Union. Through his offices with Dublin Corporation, the Vartry Reservoir water supply works were completed, introducing a freshwater supply to Dublin city and suburbs. He died at Bath in England on 9 April 1875. Shortly after his death, his contributions to the provision of the water supply, and the beneficial impact this had to conditions of public health in Dublin, were recognised in a memorial statue on O'Connell Street.

John Russell, 1st Earl of Bedford, KG, PC, JP (c. 1485 – 14 March 1555) was an English royal minister in the Tudor era. He served variously as Lord High Admiral and Lord Privy Seal. Among the lands and property he was given by Henry VIII after the Dissolution of the Monasteries, were the Abbey and town of Tavistock, and the area that is now Covent Garden. Russell is the ancestor of all subsequent Earls and Dukes of Bedford and Earls Russell, including John Russell, Prime Minister of the United Kingdom (1865-6), and Bertrand Russell, the philosopher (1872-1970).

The monarchy of Canada forms the core of each Canadian provincial jurisdiction's Westminster-style parliamentary democracy, being the foundation of the executive, legislative, and judicial branches of government in each province. The monarchy has been headed since 8 September 2022 by King Charles III who as sovereign is shared equally with both the Commonwealth realms and the Canadian federal entity. He, his consort, and other members of the Canadian royal family undertake various public and private functions across the country. He is the only member of the royal family with any constitutional role.

Royal assent and the royal sign-manual are required to enact laws, letters patent, and Orders in Council. The Constitution Act, 1867, leaves the monarch's direct role in the provinces in question and many royal duties in these regions are specifically assigned to the sovereign's provincial viceroys, known as lieutenant governors, who are appointed by the King's federal representative, the governor general. Further, within the conventional stipulations of constitutional monarchy, the Crown's direct participation in any of these areas of governance is limited, with most related powers entrusted for exercise by the elected parliamentarians, the appointed ministers of the Crown generally drawn from amongst them, and the judges and justices of the peace. The Crown today primarily functions as a guarantor of continuous and stable governance and a nonpartisan safeguard against the abuse of power, the sovereign acting as a custodian of the Crown's democratic powers and representing the "power of the people above government and political parties."

James Williamson, 1st Baron Ashton, DL, JP (31 December 1842 – 27 May 1930) was a British businessman, philanthropist and Liberal Party politician. His family's business in Lancaster produced oilcloth and linoleum, which was exported around the world. After serving as a Member of Parliament for Lancaster, he was elevated to the peerage as Baron Ashton in 1895. Unproven accusations that he had purchased his title, however, haunted him and led to his eventual withdrawal from public life.

James Chuter Chuter-Ede, Baron Chuter-Ede, CH, PC, DL, JP (né Ede; 11 September 1882 – 11 November 1965), was a British teacher, trade unionist and Labour Party politician. He was a Member of Parliament (MP) for 32 years, and served as the sole Home Secretary under Prime Minister Clement Attlee from 1945 to 1951, becoming the longest-serving Home Secretary of the 20th or 21st century.

Edward Cecil Harris, MBE, JP, FSA is a prominent Bermudian archaeologist. He is best known for the "Harris matrix", developed in February 1973 and considered by some to be the "industry standard" for stratigraphic archaeology. This was followed by a five-year investigation into archaeological practices. He determined that the methods did not properly account for stratigraphy, and published his findings in 1979 as the Principles of Archaeological Stratigraphy.

While attending Columbia University School of General Studies in the United States, Harris spent the summers assisting on archaeological digs in Winchester, England. After graduating, he continued his archaeological work, including in Bergen, Norway and along the Persian Gulf. In 1997 he worked towards a PhD through the University of London, while working on excavations in New Guinea.

Sir Charles Lanyon DL, JP (6 January 1813 – 31 May 1889) was an English architect of the 19th century. His work is most closely associated with Belfast, Northern Ireland.

Edward Hyde, 1st Earl of Clarendon PC JP (18 February 1609 – 9 December 1674) was an English statesman, lawyer, diplomat and historian who served as chief adviser to Charles I during the First English Civil War, and Lord Chancellor to Charles II from 1660 to 1667.

Hyde largely avoided involvement in the political disputes of the 1630s until elected to the Long Parliament in November 1640. Like many moderates he felt attempts by Charles I to rule without Parliament had gone too far, but by 1642 felt Parliament's leaders were, in turn, seeking too much power. A devout believer in an Episcopalian Church of England, his opposition to Puritan attempts to reform it drove much of his policy over the next two decades. He joined Charles in York shortly before the First English Civil War began in August 1642, and initially served as his senior political advisor. However, as the war turned against the Royalists, his rejection of attempts to build alliances with Scots Covenanters or Irish Catholics led to a decline in his influence.

Robert Shallow is a fictional character who appears in Shakespeare's plays Henry IV, Part 2 and The Merry Wives of Windsor. He is a wealthy landowner and Justice of the Peace in Gloucestershire, who at the time of The Merry Wives of Windsor is said to be over 80 ("four score years and upward").

A thin, vain and often self-deluding individual, used to life in the provinces, Shallow functions as a dramatic foil to the rotund and worldly Sir John Falstaff, who visits Shallow's lands on royal business, but later returns intending to fleece Shallow of his money. In the Merry Wives he visits Windsor with his relative Slender, encountering Falstaff once more.

General Sir Arnold Burrowes Kemball KCB KCSI JP DL (18 November 1820, Bombay – 21 September 1908, London) was a British Army officer who took part in the First Afghan War, the Persian War, the Serbian-Ottoman War and the Russo-Turkish War, and was British representative in the Persian Gulf and Consul at Baghdad.

Admiral of the Fleet Edward Russell, 1st Earl of Orford, PC, JP (1653 – 26 November 1727) was a Royal Navy officer and politician. After serving as a junior officer at the Battle of Solebay during the Third Anglo-Dutch War, he served as a captain in the Mediterranean Sea in operations against the Barbary pirates.

Russell was one of the Immortal Seven, a group of English noblemen who issued the Invitation to William, a document asking Prince William of Orange to depose King James II. Based in the Netherlands, he served as Prince William's secretary during the planning of William's invasion of England and subsequent Glorious Revolution. He was fully engaged in providing naval support for the Williamite War in Ireland until the war ended. He was Commander-in-Chief of the Anglo-Dutch force that fought the French fleet at the Battle of Barfleur and destroyed much of it in a night attack at the Battle of La Hogue during the Nine Years' War.
