Hi JM,
You are a good woman - just like Catharine was!

Q 1. Don't know about 1828 in Tassie - but we want to find her much earlier than that. Before 1817 - but she may well have arrived with the first settlers - just don't know. I'm told with the first settlers is highly unlikely - 'it was a penal settlement' - but - who knows?
David has trawled the musters and every list he can lay hands on - and every permutation he can think of. Apparently there were musters annually in Tasmania for the first years. I have briefly looked through some of the musters without coming up with anything new - but not nearly as thoroughly as David has done over the years he's been looking. I spent a few hours with them last Tuesday at the state library - I find reading them very difficult on the microfilm - don't know if David can see them in hard copy. I've also trawled through the Hobart Town Gazette for any mentions - so has he to a much greater degree: ditto Col. Sec's letters.
As I keep saying, I don't have anything positive to say Catharine ISN'T a convict - just that the 'family lore' to which I keep harking back, does not have her as a convict - it has proved pretty accurate to date - no other evidence at all! - But as Thomas's convict status was known, and the other convict forebears were known, and the marine's status was known, I can't see any reason why Catharine's status as a convict (if she was one) wouldn't be known too. It is negative evidence, but as strong as I can get. Why happily tell one's story and hide another?? The other reason I have for thinking she came free is that the convicts are so very well documented - and Catharine has slipped in under the radar. The convicts didn't often do that, but it seems free settlers often did.
Q 3.Yes we know about the ADB entries for Fred Stieglitz and Thomas Ransom, and the references to Catharine in them.
See nothing about being a convict there for her is there??
Q 2. There is a marriage certificate to Fred in 1830 - I have that but I don't think Catharine signed her own name - don't think Fred'k did either - it all seems to have been written in one hand - if she did sign, it is very good writing.
Still looking for any other documentation. But really, both she and Fred should have signed themselves.
Question 4 - yes
Our questions are -
1 who was she?
2 where did she come from and when?
3. Why couldn't she marry Thomas? - See reference in ADB for Thomas.
Apart from that, everything is pretty clear really!!!

Re last post - yes to the 'CATHERINE' - and all the Catherines on the 'Kangaroo' - and all the Catherines arriving in Tasmania on whatever vessel whatsoever - (and all the Catherines known to man I do believe)

Cheers we will find her . . .we WILL find her . . . WE WILL find her . . . WE WILL FIND HER!
