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".
Courtesy titles in the United Kingdom
Titles with the same name as a peer's main title are also not used as courtesy titles. For instance, The Duke of Westminster is also The Marquess of Westminster and The Earl Grosvenor (amongst other titles). The duke's eldest son is not styled "Marquess of Westminster" (which would cause confusion between the son and the father), and so is styled "Earl Grosvenor" instead. The title used does not have to be exactly equivalent to the actual peerage: the eldest son of the current Duke of Wellington is styled Marquess "of" Douro, although the actual peerage possessed by his father is Marquess Douro (not "of" Douro).
