I meant to add earlier, there is a marriage of William SAGE and Jane OSWALD on 26 October 1806 by banns (both otp) at St Mary Redcliffe, Bristol. The minister has written "Jane OSWELL", but her signature looks like "Jane OSWALD". Witnesses are James GWYER (I think) and Mary PERRIN. William signs with "x".
A possibility for Hester's parents?
Thanks again Maddy this information is brilliant and appreciated.
