There are two search facilities. Use them to find places, causes of death, occupations, and the names of ‘informants’ (those who registered deaths).
For advanced searching and detailed, Google-like results, click on Advanced Search (opens in a new window). This is the recommended option.
For more basic results, enter a surname or keyword in the search box on the right and then hit the return key. This will simply show you the pages on which your search item can be found.
