This is the Robinson family in 1861:
1861 census on ancestry
Church Street, Ormskirk, Lancashire
James Robinson Head Mar 36 Tailor Lancashire Bolton
Jane Do Wife Mar 36 Do Ormskirk
James Do Son 8 Scholar Do Do
Nancy Do Daur 7 Scholar Do Do
John Do Son 2 Do Do
So Ann / Nancy's birth should be about 1853-4. I'll have a look.
