Probably just as well we don't have Henry as a third name, Kris - we'd be trying to sort out if he was a Tom, Dick or Harry!

Richard is recorded as being born in Notts (1851 census) but Thomas is shown as born in the county (1841 census). It is possible that Thomas died late 1841-1842 (thus falling outside the burials data) and Hannah remarried. The question then is whether at the burial of Matilda in 1845, the name of her natural or step-father would be recorded. I bow to any advice on this.
There's now an explanation why 'Matilda' appears as an 8 yo in the 1841 census and a 3 yo in 1851. They are different children. Matilda I died in 1845, Matilda II was born in 1848 and given the same name.
Elaine, if it's not too much trouble, the Martin baptism/burial entries could prove useful, if only for a new lead or to confirm a theory (or to destroy it!)
Thanks to both of you for your assistance.
