Peerage of England
In the following table, each peer is listed only by his or her highest English title (with the exception of the Duke of Norfolk/Earl of Arundel) showing higher or equal titles in the other peerages. Those peers who are known by a higher title in one of the other peerages are listed in "italics".
Peerage of Ireland
The Peerage of Ireland consists of those titles of nobility created by the English monarchs in their capacity as Lord or King of Ireland, or later by monarchs of the United Kingdom of Great Britain and Ireland. The creation of such titles came to an end in the 19th century. The ranks of the Irish peerage are Duke, Marquess, Earl, Viscount and Baron. As of 2016, there were 135 titles in the Peerage of Ireland extant: two dukedoms, ten marquessates, 43 earldoms, 28 viscountcies, and 52 baronies. The Crown of the United Kingdom of Great Britain & Northern Ireland continues to exercise jurisdiction over the Peerage of Ireland, including those peers whose titles derive from places located in what is now the Republic of Ireland. Article 40.2 of the Irish Constitution forbids the state conferring titles of nobility and a citizen may not accept titles of nobility or honour except with the prior approval of the Government. As stated above, this issue does not arise in respect of the Peerage of Ireland, as no creations of titles in it have been made since the Constitution came into force.
