Another free site for Birth, Death, and Marriage Civil Registration Index is here :-
http://freebmd.rootsweb.com/
The index entries are generally filed in quarters, so :-
Quarter 1 March - Covers registrations made Jan-Mar
Quarter 2 June - Covers registrations made Apr-June
Quarter 3 Sept - Covers registrations made July-Sept
Quarter 4 Dec - Covers registrations made Oct-Dec
You should be aware of the potential lag whereby, from memory, the informant had up to six weeks to register the event. So someone born 20th March 1860 could appear in Q2 Jun 1860 Index and not Q1 Mar 1860.
Anyway good news is that both Charles Frederick Hindle and John Oswald Hindle appear on the FreeBMD list.
John Oswald Hindle's birth is given as 1871, and not 1872.
I will double check it's not a transcription error against original Index held at Family Record Office on my next visit.
