Does anyone know of a web-site or document source for Isle of Man emigrants/immigrants to Australia for the period 1841-1851 ish? I have a relative who has disappeared from the Isle of Man between the two census dates (John Fargher b Malew November 1801 - a lead miner) and is possibly among a group who are digging for gold in Adelaide (see IOM FHS Journal Feb 2006 pp33-34). Any help greatly appreciated.
