Thanks so much to everyone, much appreciated, no wonder it is so hard for the amateur researcher when you don't even know what name you are looking for, so many possibilities? I think I will stick to researching the Jane Noble born 06/12/1831 at least the dates are correct and would explain the father being deceased when she made the journey to Australia in 1852, yet to find the mothers death, was thinking if she lost her husband in 1837 and possibly had 2 children under 5 y/o life would be pretty tough. If this does turn out to be the parents I am not sure if I am going to like the outcome?
Majm, now knowing that you have transcribed for the NSW Archives maybe you can help me. I have two passenger lists for the "David Mciver" the interesting one ,I think, is from the Agents Immigrants List that was emailed to me by a friend, it states that both parents John and Martha were deceased, and on the left hand side noted against Jane's name is hospital? I don't think this list is available online? and have not yet been able to trace where to get a good copy as the headings are missing from the copy I have, I rang the Immigration archives NSW but they couldn't help.
I do know that the David Mciver was in quarantine for 40 days because of Typhus and 10 died on the voyage and 7 while in quarantine.
Kindest Regards
