I think this is the family on the 1861 census
1861 Tipton Randles? lane private William Smart h m 43 labourer
Ann Smart wife 36
Robert son 15
John Thomas son 5
Benjamin son 1
all b Tipton Staffs
that is I believe the John Thomas on the certif.
But no George so he must have been b 1861 as on the 1881 age 20 and not 1858 age 33 on 1891.
So marriage would be good for Ann and William Smart ...

and on the 1851 census to confirm that she is an Ann and not a Mary ann as there are 2 marriages
