The GRO for England and Wales has added two searchable indexes ar www.gro.gov/gro/content/certificates
These indexes are amazing in that for borths the mother's maiden name is included for the complete 1837 - 1915 (births) and the age added for deaths 1837-1957. This is an amazing improvement as other indexes (FreeBMD and Ancestry) have mother's maden name only from 1911. Ages are only given for deaths from 1867 on http://www.freebmd.org.uk/cgi/search.pl. Go find answers to those brickwalls!!!!
