My ancesters Samuel George and Elizabeth Cox left England in 1861, arriving at Melbourne. They moved to Ballarat in 1867, then onto Sydney, Where Samuel died in 1876. They had 9 children, but only mother and 3 of them returned to the Uk in 1878. I know that 4 children died in infancy, but was wondering where George Dorrell (born 1860 in UK)and Arthur Edwin (Born 1864 in Collingwood)disappeared to.

If anybody has any information, please get in contact.
Thanks
Lesley
