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".
List of viscountcies in the peerages of Britain and Ireland
The majority of viscountcies are held by peers with higher titles, such as duke, marquess or earl; this can come about for a number of reasons, including the title being created as a subsidiary title at the same time as the higher peerage, the holder being elevated at a later time to a higher peerage or through inheritance when one individual is the heir to two separate titles.
