Hello I have an ancestor who arrived in Australia aboard the "Daniel Ross" on 27 April 1855 departed Hamburg. The "Daniel Ross" passenger list lists a "Antoni Mella", however all records in Australia refer to him as Antoni Melzer Became A/an Citizen 11 Jan 1872; stated 43yrs old, & born ?Hesobists, Central Prussia. I have been at a 'dead end' now for several years. I can not even seem to be able to find where Central Prussia was/is. I thought if I found the area then I maybe able to work out the town name. Any help would be greatly appreciated. Thank you. Margaret
