Hi Fellin,
As James and Rachael do not seem to name Children Charles or Ann it may not be his correct Parents. (unless they died between censuses!)
Is this their Marriage ?;
James BEGENTS/Rachel HALSEY, 16 Nov 1824, St George the Martyr, Southwark, Surrey.
If you click on the Batch and just enter Begents there is this Marriage also there;
John BAIGENT/Mary BIFFIN, 27 May 1828
It may be another spelling of the Surname to consider and a possible sibling of James.
Hopefully someone who has better access to Records can help you
