Cambs FHS has an index on its website at http://www.cfhs.org.uk/Search.html But there's nothing that's obviously your Eliza. Could she have married by 1841?

I cannot find a John Wilson of roughly the right age to be Eliza's father in Wisbech in 1841, nor can I find Eliza herself. But I wonder whether the following entry could be Eliza's mother Elizabeth?
1841 Census
Old Horse Fair, Wisbech, Cambridgeshire
Elizabeth Wilson - 60 - Independent - b. in county
Harriett Wilson - 30 - Dress Maker - b. in county
Betsey Clemenson - 40 - Independent - b. in county
Ref: HO107 / 0079 / f.15 / p.25
Finally, and for the sake of completeness, I have found an Eliza 'Willson' of around the right age, but in Littleport, Cambridgeshire. Her entry is:-
1841 Census
Back Row, Littleport, Cambridgeshire
Eliza Willson - 25 - Female Servant - b. in county
