Based on the fact that there is a Charlotte Overall born in Great Bardfield in 1839 who emigrated to Australia (a few lines higher up the list), I assume that Eliza was born in about 1837, as she is two years older than Charlotte on the list.
Looking at the Eliza Rogers on the 1841 census, there is one born in about 1835 in Clavering, Essex. it doesn't sound anything like Claveland/Clareland, but the first five letters could be the same.
Others born at about the same time are in Wethersfield, Messing, Feering and Chelmsford. You could follow them through later censuses to see which disappear by 1861: I can see the ones from Feering and Chelmsford in 1861 as they weren't married by then.
