I have found a few leads at http://naa12.naa.gov.au/scripts/PassengerSearch.asp All but one of these I have eliminated for one reason or another by searching the passenger lists at the UK NA Kew. The one I can't find any info on is a sailing on the Nalgora from Liverpool to Freemantle arriving on 26 Oct 1928. It doesn't appear in the UK archives at all. Is there any other source I can go to to get details of this passenger so that I can confirm or eliminate him from my inquiries.
