Some Australians have been made life peers (barons) or peeresses (baronesses) of the United Kingdom. Life peeresses in England display their arms on a lozenge. Peeresses and other female armigers do not bear helms or mantlings. Children of peers (and "suo jure" peeresses) also obtain a special precedence. During the Coronation, peers and peeresses put on coronets. Hereditary peeresses were admitted in 1963 under the Peerage Act. His clients included a Royal Duke and at least twenty-one assorted peers and peeresses. However, hereditary peeresses continued to be excluded until the passage of the Peerage Act 1963. Eldest daughters do not have courtesy titles; all courtesy peeresses are wives of courtesy peers. In some, but not all cases, peeresses of first creation were created for life only. In addition, peeresses were told in 1953 that "a tiara should be worn, if possible".
