I have Joseph's christening in Stoke on Trent and Hannah's in Doncaster.
RachelJoyce, please could you say which Joseph you mean? Either way, I'd be very interested to know more about his christening in Stoke.
If you mean the Joseph Walker who married Hannah Earnshaw in 1803, we know from the 1851 census that he was born in Stoke, but I wonder how you narrowed down the options at that point? I came across a Stoke baptism on 9 August 1781 to William and Hannah Walker; is this the one you mean? (More conjecturally still, I found Joseph these siblings: Thomas, Myra and Charles.) Finally, and most conjecturally of all, the only plausible Staffs. marriage I could find between William Walker and Hannah X was on 12 February 1763, in Stoke, between WW and Hannah Simpson.
But perhaps the Joseph you're referring to, the one whose christening in Stoke you've managed to find, is a brother to the Benjamin about whom you initially enquired, ie, a son to Joseph Walker and Hannah Earnshaw. This would solve one problem: the fact that Benjamin's baptismal record identifies him (Benjamin) as the second son; that his elder brother would be called Joseph after his father would make sense (and Benjamin himself would have been named for his maternal grandfather, or perhaps for the biblical Joseph/Benjamin link). As I haven't been able to find this Joseph - eldest son of Joseph and Hannah - I'd be very interested indeed in his christening. One problem: why was he baptised in Stoke? True, his father - the elder Joseph - had been born there, but the elder Joseph was already "of Castleford" (in Yorkshire) when he married Hannah in 1803.
I really look forward to hearing more about your researches into this family over the past few years since this thread was last active. Many thanks.
