Pam,
Cheshire BMD's are searchable on-line at Cheshirebmd.org.uk.
I have had quick look and the Wattleworth's are there. There are references for the marriages of Jane emily (1871-75),Charles W. (1876-80) & James (1881-85).
There also appears to be a possible additional child John Robert b. 1853?
Also found a Charles Wattleworth age 53 in the 1901 census born Birkenhead living in the parish of Seaforth. In the 1881 census he appears to be in Ramsey IoM at 13 Albert Road (visitor).
If you get a copy of John's birth certificate (1851) it may provide an address to help your search in the 1851 census.
