Hi,
When searching through NSW bdm online, (or through compiled indexes of NSW bdm events on various websites) it can be important to remember:
1. Less is more ....
2. Any bdm could be registered at ANY deputy registrars office, NO requirement to attend the nearest one.
3. In the years AFTER civil registration started in NSW (1856) a) MARRIAGES were registered by the official performing the ceremony, b) DEATHS by the Funeral director AFTER he had been issued with interim burial order issued by police magistrate or coroner OR had medicos certificate certifying death and causes. c) It was only BIRTHS that were required to be registered by ordinary folk,
So if looking for a birth 1856-1918 (1918 being when NSW bdm started to move away from oral registration towards pro forma application forms) it can be sensible to recall parents of new babies may not be aware of their formal duty to register a birth. Not everyone could read, write, (compulsory secular education commenced 1878ish).
NSW districts were not same geographical area as Police districts, nor Pastoral districts nor civil country/parish, nor Church districts, nor local government areas.
Hence rule 1. Less is more. Put less info in NSW bdm dialogue box, study index results, pause, think, PERHAPS seek partial official transcripts.
Rhetorical questions....
Is your person the eldest child.... if so, is he listed on younger siblings birth certs? Does mum's maiden name on younger sibling's b.c. help validate the marriage cert info. If he is youngest, could he be indexed under a different surname perhaps .... could he be ex-nup of eldest sister, being raised by his granddparents...
Who were the midwives/witnesses on younger siblings births ..... family perhaps
What occupation for dad on those birth certs or marriage
Have you searched Greville Post Office directories 1872, 1875 etc...or similar directories
Have you searched 1870s 1880s electoral rolls for NSW
Have you looked for baptism record for this person...
