Frank,
Sorry, there's no trace of a Thomas PARIS in the right age-range in the Greywell PRs, the microfiche copies of which show abysmal record keeping! However, in 1841 & 1851 he gave his age as 44 & 54 respectively, producing an earlier birth year c1797, and in 1851 he gave his place of birth Basingstoke!
Please see further research results in PM.
