Hi Patricia,
Mary BRADSHAW - You have a baptism for her and her parent's names, and I presume you're happy you have the right baptism & parents. That may be all you're ever going to get, and you're relatively lucky to have it
It may be that similar is all you can eventually hope to find for John.
They were both born before the start of Civil Registration, therefore there is no central civil registry recording the actual births. Prior to Civil Registration (from 1 July 1837)you are looking for baptisms or christenings - BUT such records were not always made or kept, or not always survived.
You have the added 'complications' of:
Catholic & other non-conformist religions who often did things differently, or baptisms which occurred years after the birth, or baptisms which didn't even necessarily occur in the parish (or country or county) in which the Birth occurred. Some priest/clerks/religions/parishes recorded the Baptism AND included the date of Birth on the record - but it wasn't a requisite.
If you come across her Birth date mentioned in a family bible, a will, a newspaper 'intimation', or other documentation such us immigration documents, naturalisations - that would be good luck.
If you have her recorded at certain times of her lifespan (census', death, etc) with an age, then you can at least determine if was or was not likely born close to the time she was baptised.
If you can find baptisms of siblings, marriages of parents, UK census, etc that all helps make an accurate determination of where she born.
Cheers
AMBLY
