Thanks to all,
Right, I have Theresa Ann Nelson, born Owston 1863, parents Robert Nelson, born Owston, 1834, mother known as Marena/Maria/Mary Rampoldi, born Althorpe, 1836.
Theresa gives birth to a girl listed as father unknown, and the child is listed in the Owston baptisms register on 14 July 1881 as Sarah Elizabeth Nelson.
Theresa marries Wootton Torn in 1882, and on the 1891 cencus, Sarah is not living with them. I was trying to find out if she was living with her grandparents.
Hope this helps,
Pat.
