I located a profile on Find-a-Grave for a Clarence Otis "Jack" Melton, born 3 Nov 1913 in MO, died 20 May 1993 in MO, married Madge Rains (1916-1993). It has him as the son of William T. Melton (1882-1953) and Effie L. Jeffries (1892-1979). See here: http://www.findagrave.com/cgi-bin/fg.cgi?page=gr&GRid=23859917
Another site shows Effie Jeffries as the daughter of William Spencer Jeffries (1859-1942) and Sarah "Sally" Atwell (1865-1945). William is shown as the son of Elzie Jeffries and Elizabeth McKinney. The pedigree continues on... If you have access to ancestry.com, it's here: http://trees.ancestry.com/tree/7070655/family/pedigree
