Why is mother's maiden surname included on some statutory deaths index results and not on others?
Mother's maiden surname appears on most original statutory deaths register entries (if known by the informant). However, it was not captured on the index to statutory deaths until 1974.
The NRS are in the process of adding mother's maiden surname to the pre-1974 index, starting with the earlier entries. (Occasionally you may find it recorded in later index entries, but this is due to individual record updates).
Important: The availability and treatment of the mothers maiden surname is dependent on the year(s) searched:
1. Searches 1855-1965 (records more than 50 years old)
If you enter a mother's maiden surname and this information has not yet been indexed, the record will not be found. To ensure that all entries where the mother's maiden surname has not yet been captured in the index are returned, please check the Include Unrecorded Mother's Maiden Surname box. Be aware that this may greatly increase the number of possible matches.
2. Searches 1961-2014 (records less than 50 years old)
For security reasons, restrictions have been placed on modern deaths index searches which include the Mothers Maiden Surname, and on the results of such searches.
Restrictions are as follows:
- If you enter a mother's maiden surname, the record will not be returned because this information has not yet been added to the index.
- All records returned will show Not Permissible in the Mothers Maiden Surname column, although the information will be visible on any extract ordered (if known by the informant).
- Mothers maiden surname is present in the index for these years.
- As a security measure, wildcards are not allowed - if you enter a mothers maiden surname, it must be an exact match for the information in the database or the record will not be returned.
- If you search without entering the mothers maiden surname, all records returned will show Not Permissible in the Mothers Maiden Surname column, although the information will be visible on any extract ordered (if known by the informant).
