Yes you have the correct person, and yes the other 2 were transported as well.
Alice later married in Tasmania, and I guess went on to raise a brood of children -I wonder if she left children behind in England?
Joseph was sent to Maria Island for his bad behaviour and around 1853 absconded, and from what I have so far managed to find doesn't appear to have been recaptured.
Abraham received his ticket of freedom in 1853 and quickly left Tasmania for Victoria.
I had miss the younger children on the census, actually it is the 1851 census that I had found Sarah and Elizabeth. Sarah had 'remarried' and Elizabeth was listed as Elizabeth Firth and I don't remember seeing the younger children, maybe they had died in the intervening years?
Gives me some new leads to follow up on, may prove interesting either way.
I am yet to decide if Abraham was a willing participant in his brothers crime or the unsuspecting patsy in it all.
According to Abraham's death registration in Australia his profession as a cloth weaver. Something he never did in Australia, it's not sure how much truth there is in a lot of the information that has been carried through the following generations. To put it politely the truth was never allowed to stand in the way of a good story. It seems a lot of both Abraham's and his Australian wife Mary's history was sanitised to overlook that he had been a convict or when Mary actually arrived into Australia.
In regard to actual birthdates and parents names - allegedly his father was also Abraham Firth, mothers name unknown, and we had thought he was born c1813 the actually date unknown. Still looking for any information that will expand on this. The 1841 census will be worthy of a closer examination. Thank you all.
