This may be futile but...
James Nimmo was a Presbyterian minister. During the 1850s and early 1860s he worked in the Hunter Valley, NSW, Australia. He presided over my ancestor's third marriage in a private house in either Newcastle or Maitland. (The first two marriages were made before compulsory registration in NSW.) The NSW BDM registration has not recorded parents and his descendants would love to know who they were. Unfortunately James Nimmo left NSW shortly after this and on google I have traced him to Victoria, Canada, by 1863.

HE TOOK HIS REGISTER WITH HIM! I have tried St Andrew's Archives in Australia and the SAG church register records and neither have a record of the existence of Nimmo's register. I'm not particularly interested in the man and know the chance of finding the register is 'Buckley's and none' but thought I might ask advice - 'cause I need it! Is there any hope?
