And in 1881, RG11, piece 1597, Folio 49, Page 24, we find at Chapel Street, Crowland:
Middleton, Mark Head M 39 Mailcart Driver b Stamford, Lins

Middleton, Ada S Daughter F 10 b Crowland
Middleton, Robert M Son M 5 b Crowland
Middleton, Emily J Daughter F 2 b Crowland
Middleton, James H Son M 6 months b Crowland
Sharpe, Mary Mother-in-Law F 70 Parochial Annuitant b Crowland.
N.B. Census return is enumerated in Peterborough, Northamptonshire!
Personally I think it's a possible match on the family.
Where did the original marriage info come from?
How do you know that Emma's maiden name was Hall?
