English: status name for a steward or official, from Middle English bailli ‘manager, administrator’ (Old French baillis, from Late Latin baiulivus, an adjectival derivative of baiulus ‘attendant, carrier, porter’).

English: habitational name from Bailey in Little Mitton, Lancashire, named with Old English beg ‘berry’ + lēah ‘woodland clearing’.

English: occasionally a topographic name for someone who lived by the outer wall of a castle, from Middle English (Old French) bailli ‘outer courtyard of a castle’ (Old French bail(le) ‘enclosure’, a derivative of bailer ‘to enclose’). This term became a placename in its own right, denoting a district beside a fortification or wall, as in the case of the Old Bailey in London, which formed part of the early medieval outer wall of the city.
