Hi Chiapet
Marriage found at
http://www.familysearch.org Thomas Barnes and Jemima Oliver, 9 May, 1831, Ninfield, SussexPerhaps a lookup of the 1841 census would give you an approx age for John Barnes' mom, Jamime, this may be her?
Jemima Oliver, christening, 1 Jan, 1812, Ticehurst, Sussex, parents, James Oliver and Ruth, she'd be about 29 in 1841.
This may be the marriage of Jemima's parents.
James Oliver and Ruth Roberts, 12 Feb, 1797, Ticehurst, Sussex, and then possibly 11 siblings born to James Oliver and Ruth, starting with Mary, c.1798, ending, George, c.1817, Jemima, c.1812, being child #9, all christened, Ticehurst, Sussex (sent the other names and d.o.c via PM)
A marriage for Eliza's parents?
Richard Ticehurst and Jenny Starr, 6 Jan, 1819, Hollington, Sussex. matches the link given above.
As Ros said, don't take this as gospel, it's a quick run through of information located at familysearch.org and would of course need to be verified.
Someone on the Sussex boards may be able to do that 1841 census lookup for you.

Happy Hunting
