Ron, your problem may be the same as one which had me flumuxed for a few years.
There is a 50% probable marriage in Q3 1852 Tynemouth 10b 192 between Joseph
Tunnicliffe BAINS and Sarah
STAFFORD.
So try looking for the baptism of a Sarah E. A. STAFFORD - the illegitmate child of Sarah
STAFFORD who later married Joseph
BAINS and therafter was know by the surname of her stepfather.
You might also find Sarah
STAFFORD and her mother Sarah
STAFFORD in the 1851 census.
