Thank you for confirming that detail re Daniel Herbert for me. I wonder whether there is the record of his sibling's death in the weeks before his birth ... if you could find that for me please.
My research is the Ross Bridge in Tasmania where Dan was the convict overseer. The bridge is unique in the world owing to its 180 carved archstones and 6 keystones. Most of them have been attributed to Dan Herbert, transported for highway robbery in Saddleworth Yorkshire, in 1827.
I cannot find a record of his apprenticeship; I can only suppose he gazed up at the hunky punks and maybe went to Bath to be influenced and impressed by stone carvings.
