I posted a lot of the info about Daniel on the Convict website.
James Leitch and Isabella md Alexandria, information gained from death certificate of James and Isabella's daughter Isabella Harriett Yeo. James was a captain of trading and whaling ships. Isabella's father,Captain David Dawson, also ships captain often took one or more of his daughters with him on his voyages. Both Leitch and Dawson from Scotland. Leitch could very well have been crew member on a Dawson ship before gaining his captaincy or the couple could have met in port. Won't know until research reveals connection. Trying to find marriage registration which is proving difficult. Their children were John Dawson Leitch, sailed to America not heard from again; Mary (my Great Grandmother) md Duncan Lamont in Bathurst, Isabella Harriet md William Yeo, Bathurst. Youngest 3 children, David, Frances and Lucy Leitch, went with mother Isabella when she left James and partnered with Daniel Marley in Victoria where the twins were born. Eldest son went to sea and 2 eldest daughters raised by James' sister, Jane Whitton, in Bathurst. I have a lot of info on these girls, the Leitchs and the Dawsons.If you want this info, let me know.
