Hi there,
Do you have copy of the 1874 marriage, (#2448) registered Goulburn district? If it has those elusive blanks for his parents details, can you please advise the denomination/clergy who conducted the ceremony, as from that information it should be possible to seek out the original parish register which should show ALL the information given by the bride and the groom when seeking to be married.
See
