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".
Baron de Ros
Baron de Ros (pronounced "Roose") is the premier baron in the Peerage of England, created in 1288/89 for William de Ros, with precedence to 24 December 1264. (The spelling of the title and of the surname of the original holders has been rendered differently in various texts. The word "Ros" is sometimes spelt "Roos", and the word "de" is sometimes dropped.) "Premier baron" is a designation and status awarded to the holder of the most ancient extant barony of the Peerage of England. The present premier baron is Baron de Ros. Before the Dissolution of the Monasteries the Prior of the Order of St John in England was deemed premier baron.
