Hi Barbara I just checked Mariners and ships in Australian Waters - http://mariners.records.nsw.gov.au/search.htm - and William Wathem is listed on Kate Conley's voyage Port of McKay to Sydney, May 3rd 1875, Deserted. Must have been a fun trip - 2 other deserters and one Martin Sarsen sent to Gaol. Search the site - you should come up with other vessels he sailed on. Cheers Barbara
