Peerage of England
The ranks of the English peerage are, in descending order, Duke, Marquess, Earl, Viscount, and Baron. While most newer English peerages descend only in the male line, many of the older ones (particularly older baronies) can descend through females. Under English inheritance law all daughters are co-heirs, so many older English peerage titles have fallen into abeyance between various female co-heirs.
Supreme Court of the United Kingdom
New judges appointed to the Supreme Court after its creation will not necessarily receive peerages; however, they are given the courtesy title of Lord or Lady upon appointment. The President and Deputy President are appointed to those roles rather than being the most senior by tenure in office.
