Transporting convicted persons beyond the seas to New South Wales effectively ceased in 1840, but there were two chaps with the surname HOULT who had arrived under sentence, Edward, per the Royal Admiral back in 1792, and Henry per the Asia (5) in 1825. Two with the surname HOULT arrived as garrison soldiers ... Thomas arrived with the Second Fleet and Richard arrived 40th Regiment in 1824.
Re the surname HOULT, when checking NSW records, you should consider the lack of standard spelling ... and the longhand script ... so do always consider HOLT and HALT and other variations.
Re marriages registered in the 1870s, 80s, etc in NSW regional localities including Tenterfield, but anywhere outside of the Sydney Metro area ...
Civil registration commenced March 1856. For decades after that a dispute rumbled along between the colonial admin and the churches, simply because of the depth of detail the civil admin required on the m.c. registrations. In many instances the NSW BDMs records are deficient, lack the vital info family historians rely on. This is because the NSW BDM Registrar General did NOT receive a full record of the marriage, ie what is on the parish register is often far more detailed than the NSW BDM cert. This very well known aspect is noted on the NSW BDM website, and most family history groups in years past were busy transcribing their local churches records.
Here is a thread that may help determine where to find the original church register for the marriage in 1876, registered Tenterfield.
http://www.rootschat.com/forum/index.php?topic=546609.0I suggest that an official transcription of the Tenterfield marriage will have all the info as per the NSW BDM register, and is a better option for the official transcribers will be familiar with the handwriting of the scribe.
