This is off top of my head, just off to Launceston for propoganda forum on the benefits of allowing farmland,water resources, roads, and cultural landscapes be given away to plantations financed byAustralian taxpayers for the benefit of timber companies--but can grab time to check HRT -Historic Records Tasmania.for musters , but this time looking for a McNally not a Ransom, a McNally with a wife, old daughter, mistress, someone available to catch Thomas eye.
No- there was a gap between arriving Sydney from Norfolk, and going to Hobart.The Kanagaroo left Hobart in middle of 1814 ( April?) under Charles Jeffreys and never got there,he wandered here and wandered there and eventually returned to Sydney claiming bad weather,lost his way, it was a more scenic cruise the way he went, whatever. Authorities a bit pissed off, and sent him off again, in August from memory.Really should know these date as well as my birthday, but Al Z says the general drift is OK for the moment.
The NI connection with Thomas is so strong that you would believe that was where Catherine was sourced, a daughter or a widow or discarded mistress of a NI man,but I thought I had checked this out years ago, looking at ages, initials, cross checking unspoken for birds etc. Bear in mind NI was settled 1788 so Catherine , under whatever name, would have to have been one of the ist born there,and therefore traceable. Which was why I fell for the Catherine married Brian met Thomas through Brian and Brian was leaving/had had enough of Brian alternative.
Keep thinking
