thank you so much for this Tania. I have never done any research in Queensland so did not realise the resources that are availabe (or indeed where to look).
Now I have a great outline of what happened to the 2 sisters once they came to Australia.
I was confused with the Chinese connection but when I checked the map noted that there were goldfields up around this area.
Amazing what you can find on an Irish Catholic girl coming to Australia.
Once again, many thanks
