Kew of Northborough Northamptonshire England

I'm looking for the parents of Mary Kew born 1813 Northborough. Her parents were William and Eliza according to her baptism records, but then they seem to disappear off the radar, no baptisms, marriage or deaths. Mary married Inkley White in 1834 at Stanground but her parents are the headache. anybody looking for the same family!!! I would love some help
