BEFORE you order any further NSW BDM marriage certs for any marriage 1856-1895 era… I strongly suggest that if you need marriage cert in that era, you order the Official transcription (a full one, not a partial) See:
http://www.rootschat.com/forum/index.php/topic,546609.0.html Some info re “colonial Divorces” …. This is full of important information … particularly where you can be looking for a burial for a spouse, to explain a second/third marriage, and suspect there was simply an informal ending of the first marriage…
http://www.aifs.gov.au/institute/seminars/finlay.htmlhttp://www.bdm.nsw.gov.au/bdm_fh/bdm_rec.html Important …. If the NSW BDM reference starts with “V” it is NOT a civil registration, so it is NOT a birth/death/marriage. So order the Official Transcript (because you do NOT get the real deal cert for "V" records from NSW BDM anyways...
The “V” stands for VOLUME, and it is therefore an Early Church Record. So it is either a Baptism, Burial or Wedding recorded in a parish or local church register. The event may have been celebrated in one church (of any denomination) and the information then TRANSMITTED to that denomination’s Head Church, or even transmitted to the NSW Chaplains and thus transmitted to the Church of England’s registers.
NOT ALL the records from that pre civil registration era were kept in safe places and so many were lost BEFORE civil registration commenced. Once civil registration commenced, then the local district registrars were expected to foreward returns on a regular basis to Sydney via ORDINARY mail.
Sometimes that did not happen, sometimes the returns were lost in the mail, and sometimes the records may well have been lost in the Sydney Registrar Generals Office.
Of course, todays registrations are handled electronically, so it is hoped that future family history buffs will find things a tad easier.
