Thomas who died 1843 did make a will, it's indexed on the Cornwall Record office website and the wills themselves can be accessed via FamilySearch. Thomas leaves everything to his wife Johanna and after her to all his children, share and share alike, no names given, so no help there!
http://crocat.cornwall.gov.uk/DServe/searchpage.htmAgree with you that there seem to be some missing baptisms and that Thomas who died in Kenwyn seems to be most likely father. His address in 1841 was in Lemon Street so probably comfortably off.
