I have looked at my information and at the IGI but I don’t have anything that will help your search at the present time. It would be useful to try and find the family on the 1851 census - I presume they would be somewhere in the York area. Perhaps the York and District Family History Society have published some of the 1851 census details for their area - you might be able to enquire of them what places they have covered.
