Staveley
IGI batch C055751 contains Christenings for the above children (plus some older ones). Sarah is shown as Sarah Elizabeth in the IGI entry and her Christening date is 16/07/1848
Because of the Christening date and also because Staveley fell within the Chesterfield Registration District. I wonder if this might be her Birth Registration rather than the Rotherham one 1848 Chesterfield JAS quarter 19 501
