Charlton m
English: transferred use of the surname, used as a given name largely as a result of the fame of the film actor Charlton Heston (b. 1924; Charlton was his mother's maiden name). The surname originally denoted someone who came from one of the numerous places in England named in Old English as the ‘settlement of the free peasants’, Old English ceorlatun. The first element of the placename is ultimately connected with the source of CHARLES (SEE Charles).
