Note:  It is not uncommon to find that a Birth date on the State Register is post the Baptism dates on the Church record.  Births were often registered on the State Register weeks or months after the said Birth date.  The Baptism date appears to be more accurate.
It was necessary to pay a registration fee to register a birth.  You were fined if a birth was registered late so to avoid paying the fine some families gave a date of birth for the child later than the actual date and such can result in the baptism date predating the birth date in the records, (and causing confusion for some researchers).
