I have found this family in 1871 census as follows:-
William Altoft; Tailor b 1810 Burringham
Maria; wife b 1810 Eastoft
Mary A; daur b 1852 Eastoft
1881 census shows
William Altoft; Tailor & farmer b 1810 Burringham
Maria; wife b 1810 Eastoft
Kate E; granddaughter b 1874 Epworth
There is another daughter Eliza Jane Altoft b 1854 Epworth
and a son John Henry Altoft b 1848.
Would like the earlier census records to tie family together.
