And just to add a happorth - The Government and the GRO working together are in the process of producing a database which will contain ALL useful (to whom?) data about a person.
From the moment of birth, when the entry will be made probably by the hospital, the name will only be needed as confirmation later when the birth is registered by the parent to match up with the entry, following through other moments in life, including NI numbers, marriage, death etc.
This will be happening in the foreseeable future.
