Jane's sister Hannah age 30 is in Malton for the 1841 census and there is a Jane Child age 20 at the same address (HO107/1264/3 fol 9 page 10, the address looks like Yorkersgate). Could the surname "Child" be a freudian mistranscription? I've not checked to see if she pops up in 1851, or looked for a baptism, but if there's no other trace of her then perhaps she's your Jane.
I don't have any of the other Malton pages for 1841 (only downloaded the one of interest) but have you tried trawling through them?
