There are two charles Whorral within a couple of years of each other,i am taking it as the one you mean has mother elizabeth and sibblings mary and william if this is so. then i think in 1851 the name has dropped the H and the last L and became Worral, leaving the following people still in Warwickshire,
Elizabeth worral age 51 born 1800
William age 23 born1828
charles age 17 born 1834
lucy jefcote age 11 born 1840 niece
All these ages are said to be about, so i think this may be your's, mary would be of age where she may have married by 1851 , please let me know what you think
