Back to the drawing board (from tackling this at a different angle):
1842 Deaths (same volume and page, suggesting same or similar time): Lucy (aged 66) and William (aged 73).
1842 Birth - Philliss Elizabeth (MMN Noakes)
1843 Marriage - Frances Terry
1845 Birth - Caroline (MMN Noakes)
1846 Birth - John (No mother's maiden name - so it would probably be Terry)
1848 Death - John (aged 32)
1849 Marriage - Lucy
1852 Marriage - William
1854 Birth - James Thomas (No mother's maiden name)
1855 Marriage - Charlotte
The John born in 1846 is on later census records.
The 1842 burials of William (6th March) and Lucy (15th March) are in Bexhill
1848 burial of John is in Bexhill (though his age is listed as 22).
Marriages:
Frances Terry (daughter of William Terry) marries William Smith in Bexhill in 1843
Lucy Terry (daughter of William Terry) marries James Cruttenden in Bexhill in 1849
William Terry (carman of Camberwell (son of William Terry) marries Elizabeth Saxby in Battle in 1852
Elizabeth Saxby doesn't seem to have an illegitimate son that could have taken the Terry surname.
I'd say that Terry is not that common a name in the Battle Registration District other than a family in Bexhill.
I'd also agree that the marriage certificate to Jane Butcher would be useful.
I'd also suggest using DNA if you can.
