Births Sep 1879
FISHER Sydney Everest Wandsworth 1d 725
In 1879 the registration district for London & Surrey was 1d, so I would think he is a likely one to check if you can afford the cost of the Certificate. The 1d 725 reference numbers are what you will need to get the Certificate.
I assume you have seen where the family was in 1881? It certainly confirms Sidney as being born 1879:
John FISHER Head M Male 32 Bury St Edmonds, Suffolk, England Carman
Harriet R. FISHER Wife M Female 35 Marylebone, Middlesex, England
Alice FISHER Daur Female 7 Sutton, Surrey, England Scholar
George FISHER Son Male 5 Sutton, Surrey, England Scholar
Sidney FISHER Son Male 2 Sutton, Surrey, England
Henry FISHER Brother U Male 22 Bury, Suffolk, England Carman
