Many thanks, Tim. What a great resource to be able to research from home!
I am from NSW and back from my great-grandmother also have a connection to Tasmania, so this is just perfect.
I have already found my great-great grandfather A J Potter in 1886-1887 as a draper. This must have been very soon after he arrived in Newcastle. A most interesting character in family folklore.
Added: By 1889-1890 back to more regular professions of watchmaker/jeweller.
