From July 1837 all births, marriages and deaths in England and Wales should have been registered with local registrars whose registers are, except for marriages, more informative than parish registers held at Record Offices. A copy of the index to births, marriages and deaths from 1837 to 1990 is available at Brighton Reference Library . Some cemetery registers are available at this office. A list of them is at the back of the Guide to Registers. Census Census returns are a useful source of genealogical information.
