Burke’s Peerage was established by John Burke in London in 1826 during the reign of King George IV. Since then, it has become the definitive guide to the genealogy of historical families worldwide. These include the Peerage, Baronetage, Knightage and Landed Gentry families of the United Kingdom, the prominent families of Ireland and the Commonwealth of Nations, the Imperial, Royal and Mediatised families of Europe and Latin America, the Presidential and distinguished families of the United States, and the ruling families of Africa, the Middle East and Oceania.
