Thanks again for your ongoing help, Peter. I'll follow up your advice regarding emailing the Cheshire RO.
Regarding the 1841 Census, Louisa Willcock aged 14 would probably be the great grand daughter(?) of Elizabeth Eardley. Louisa's mother is Sarah Willcock (nee Eardley) in the other Census you supplied. Sarah's mother was Mary Eardley (nee Badcock), so that's why I presume Elizabeth could be the great grandmother.
