kimmit - censuses generally began in 1841 and then every 10 years. Joanna died in 1827 aged 45 and it looks as though William then re-married to Susanna. So, as William then died in 1845, there won't be any other census apart from the one that rosie99 showed you from 1841. There was an 1831 census taken for Tiverton, but records only numbers of males and females and has no useful data.
I did check Tiverton baptisms and there are none for a Charles JACOB(S).
