Hi Annie,
I'm so sad to hear Angus has passed away!!
He was so incredibly helpful to me in so many ways. I know that Charlotte and Amelia both left for Tasmania from Leith, Scotland in 1832 so they were never on Guernsey. They were nieces of Hugh's sisters who married soldiers in Guernsey. Hugh's sisters and mother all went to Guernsey between 1826 and 1828 because they were still in Scotland before 1826. One sister married in 1829, the mother died in March 1830, and the other sister married in 1830 as well. Hugh is not anywhere in the picture. His 2 daughters Charlotte & Amelia would have been in Scotland or England. I know the exact date they left Leith and arrived in Tasmania too. Hugh was such a strange man. Disappearing for years without a trace and then reappearing in a completely different place.
