Thanks for your thoughts Liz, I have wondered if somehow it was meant to say City. As yet I haven't found the likely parents, John and Ann Pool(e) on any census or a marriage for them. There are Trees on Ancestry that claim John was born in Luxborough, which is quite possible as Joseph turns up there by 1841, also on Josephs marriage cert. one of the witnesses is Sarah Heard and these trees have a Sarah Heard as the mother of John, so a possible relation there.
I have contacted a couple of the Tree holders on Ancestry but they haven't given me any info. regards sources, hopefully I'll get there one day.
