Hello Joy
I have a few things for you that I found today. Firstly, from the Convict Indents, various details for William and John Tuck and Sarah Rumble/Rumball. If you can PM your email address I will send them to you.
Also, these:-
Ticket of Leave/Pardons - Sarah Rumbal, John Renwick 1838
Number. 47/266, Reel. 960, Shelf. 4/4212
Female Factory Records - Sarah Rumble, John Renwick 1838
Assigned to Henry Harvey, Field of Mars
Ref. 43/5255, Shelf. 4/2610.1, Year 1843
Sarah Rumble, John Renwick 1838
November 1843, disobedient, 10 days solitary confinement
Ref. 43/8830, Shelf. 4/2610.1, Year 1843
You will also see a reference to a Mary King, Sarah's daughter, who was also transported but she was not on the same ship. I didn't find anything on Samuel and there were entires for several William Tucks but would have to look further to find your William from the Portsea.
