Thankyou Merlin, the information you have given me on Thomas is really helpful especially the fact that he lived in NZ. Thomas had a twin brother named Henry and I am sure you are correct that the whole family came to NZ. I have yet to check all this out. The twins sister Helena (Ellen), calculated on dates I have, was 15 at the time of coming to NZ and I could not imagine her coming on her own. My resources to check are very limited at this time, due to ongoing major earthquakes causing damage to our main library. However, I am attempting to find out more on their parents Mary Ann Caulfield and Edward Roberts and when or if they actually emigrated to Australia from the UK, had their children (all born in Ballarat) before coming to NZ. Once again thankyou.
