Originally a short form of Kimberley, now established as an independent given name. The hero of Rudyard Kipling's novel Kim (1901) bore the name as a short form of Kimball (a surname used as a given name). In recent years, as a girl's name it has been borne by a number of well-known people, including the film stars Kim Novak (b. 1933) and Kim Basinger (b. 1953).
English: from Middle English more ‘moor’, ‘marsh’, ‘fen’, ‘area of uncultivated land’ (Old English mōr), hence a topographic name for someone who lived in such a place or a habitational name from any of the various places named with this word, as for example Moore in Cheshire or More in Shropshire.
