I am in Papua New Guinea at the moment and all my files are back in Australia.
However, I can't recall seeing any record of a Troughear being transported (and I have looked at Australian records over a number of years). But I am not as familiar with the LiverpoolTroughears as with the main lot in Cumberland, though it is possible. I'll look into it when I get home in December. I think convict transportation ended about 1860, and the last convicts from England were sent to Western Australia. There are a number of stone masons and joiners in the wider family.
