HI,
This is one piece of information checked out early in the saga.And her old BAileey record has also been supplied and discussed. The general agreement is that this is not the Catherine Christiana being researched. I have just spent time rereading all the posts from the very first trying to brainstorm more ideas about where to look.
Of course not all records are aailble online for convicts in the UK and unless you kneow where they were convicted and can contact local agencies then you are unable to follow that path.
Most convicts were well documented after their arrival in Australia.
Most marines/soldiers etc were well documented up unil they left the service and then things get hard to trace.
Most of the times their wives and families were not recorded at all or merley Mrs??? and children.
Most early free settlers were not documented at all merely listed as passengers etc and unless you are fortunate enough to find a newspaper report, gazette listing, or name in a government file re land, muster etc then tracing them is almost impossible.
We have term for our unexplained ancestors
"swimmers" how else did they get here?

I still have a swimmer to find back in 1825/1826 aged 7!!! Must have been really fit!!
Wiggy, I'm still cogitating abut getting nowhere yet.
regards
Robyn
