Hi Val
These are the children I see born to John Williams and Sarah Leonard (apart from John Isaac) in Australia
Emily 1861 Ballarat ref 1940
James Leonard 1863 Melb ref 9608
Herbert Henry Melb 1865 ref 16977
I don't see a Thomas - but I have the AVRI and wildcard searches & ref number searches are not easily done
It seems they may have moved to Melbourne for the latter part of their stay in Australia. Perhaps they came a little late looking for gold Sue - did not like life outside a large city -

- but I am guessing. Many people returned because they so missed the family connections - they still do in current times.
