Yes its well strange baptisms state Mother is Elizabeth.1841 children fit and Father but Mother down as Sarah then 1851 same Father,same address Mother back to Elizabeth.
The marriage to Sarah Riley isnt the right one childrens dates dont fit and their is a John and Sarah having children from 1817 onwards in Basford.
So we need to find Elizabeths marriage to John Grocock around 1813 its not in Basford have checked shes from Bingham in the 1851 so a possible place to look.
