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
Any woman who marries a peer uses the feminine version of his peerage title, even if her own precedence is higher than his, as in the case of a duke's daughter marrying a baron, because a peerage is a substantive title, the usage of which is preferred to any courtesy style - unless she marries into the Royal Family. If a woman marries the younger son of a duke or marquess, she becomes "Lady ["Husband's given name"] ["Husband's surname"]." If she marries the younger son of an earl, viscount or baron, she becomes "The Hon. Mrs ["Husband's given name"] ["Husband's surname"]."
