Burke's Peerage, Baronetage & Knightage is an authoritative, in-epth historical guide to the titled families of the United Kingdom. Founded in 1826 by British genealogist John Burke, and continued by his son, Sir John Bernard Burke, Burke's Peerage is one of the most recognized names in genealogy. Revised editions were published annually between 1840 and 1917 and again between 1923 and 1940, with sporadic editions thereafter. The 105th edition, published in 1970 under the editorship of Mr. Peter Townend, was the last authoritative edition for almost 30 years. Under new ownership, a 106th edition came out in 1999, and a 107th in 2004, edited by Charles Mosley.
