Something to bear in mind if you find infants – 1 could be 1 month or 1 year.
The GRO also has birth and death indexes available to search. At one point there was a project to digitalise births and deaths but it got canned. However, the project did result in an update to the indexes. Birth registrations now include mother’s former names (previously only available after 1912) and death’s include age at death. Note, it’s not recorded whether this is in years or months. Something to bear in mind if you find infants – 1 could be 1 month or 1 year.
