I am a great grandaughter of Emma Simonetta Croal. Emma came to Australia and married George Frederich Reiser 01/12/1870. I have not been able to find when she came to Australia. Emma and George had six children, Charles (my Grandfather), William, Louisa, Albert, Julia and John. George had a wife before Emma also called Emma. Emma Croal died 9/6/1892, Canungera, Queensland. Emma (aged 16) scholar and her sister Anna N. (aged 13) scholar were listed on the UK census 1861, Berkshire. Have not found any more info on them in Berkshire.
I have now found Emma came to Moreton Bay December 1869 on board the ship "Light Brigade"
