I'll be nearby in mid-Dec and also just love visiting TNA. It's such an attractive site. I'll try ordering up the original for the reasons given.
For your benefit, possible supporting evidence?
Charles Adams baptised 21 October 1819, Masbrough, may be missing from images 12, 13
Doesn't seem to be indexed on findmypast or ancestry, but it is on FamilySearch.

So as TNA is a FamilySearch affiliate library you can look at the digitised microfilm on FamilySearch on the computers at Kew.
Births and baptisms of Masbrough, Independent Church, 1758-1837
Microfilm 828144 Items 11-12

But FS do not index an Elizabeth Swan baptism at Masbrough circa 1820.
Only Elizabeth Swann in 1797, that one is on the pay sites.
