Looks like Jane on 1851 census, but born Hertfordshire. I have found a lot of discrepancies between county of birth in 1841 and actual place. The enumerator only had to put Y or N in column for born in county of residence and mistakes were easily made. Also parish of residence prior to marriage can be a long way from birthplace
