FreeBMD

FreeBMD is an ongoing project offering free access to the civil registration indexes for England and Wales 1837-1983. Currently 337+ million records are available plus access to scanned images of the original indexes. This great site is fully searchable and is regularly updated with new material.
TIP: To select and deselect multiple choices hold down CTRL as you click the mouse. It can be useful to search the Births and Deaths simultaneously as those who died in infancy and early childhood are easy to spot. Age at death is listed from 1866. Prior to that use the GRO birth and death index at https://www.gro.gov.uk/gro/content/certificates/
