The Order of the Garter is made up of a very small number of people. This group includes the Sovereign (the King or Queen of Britain) and no more than 25 full members. These members are called "Companions". Male companions are called "Knight Companions". Female members are called "Lady Companions". There are also a number of extra members known as "Supernumerary" Knights and Ladies. These members are usually members of the British royal family, and monarchs of other countries.
