Hi Jim,
I didn't have much luck with the 1851, I could only find three of them.
This appears to be Susan & Jonathan in 1851.
Edward NICHOLSON Head U 42 M Druggist Est Dereham-Nfk
Susan WARD Hskp M 50 F Housekeeper Dereham-Nfk
Jonathan WARD Neph U 14 M --- Dereham-Nfk
Address: Shipdham Road, Mitford
Census Place: Yaxham Mitford, Norfolk
PRO Reference: HO/107/1824 Folio: 181 Page: 6 FHL Film: 0207478
And this entry is a possibilty for Thomas Snr, (at the end of the household)
Thomas REDGRAVE Head M 33 M Farmer 100 Acres Emply 2 Lab Hardwick-Nfk
Mary Ann REDGRAVE Wife M 28 F --- Pulham-Nfk
Sarah Jane REDGRAVE Daur - 5 F --- Starston-Nfk

From the 1861 I found these possible entries, although some of the ages aren't quite right!!
RG9/1242, F7, Pg9, Sch47.Hole in the Wall, Church St, East Dereham,
Maria Ward, Head, U, 30, Shoebinder, East Dereham.
RG9/64, F71, Pg17, Sch44.218, Regent St, Westminster,
Hannah E Ward, Servant, U, 29, Saleswoman, East Dereham.
RG9/12, F66, Pg24, Sch148.16, St Petersburg Pl, Paddington,
Susan Ward, Head, W, 60, Proprietor of Houses, East Dereham.
RG9/3701, F40, Pg23, Sch124.North Gate St, Hartlepool,
Edward Ward, Lodger, W, 35, Shoemaker, Norwich, Norfolk.
RG9/373/ F47, Pg17, Sch88.4, Wandle Ter, South St, Wandsworth,
Jonathan Ward, Lodger, U, 33, Shoemaker, East Dereham.
I think this is the right Jonathan as I found him again in 1871 in Wandsworth & the age was correct. Maybe the enumerator misheard him & put 33 instead of 23.
Hope this helps,
Clare.
