JohnV - I have prepared family trees for both of my grandsons, Tyler Bickhoff and Mitchell Baker.
Both have a starting point as far as Australia is concerned with this ship's voyage in 1847.
Both the Bickhoff and Klopper families have had detailed histories prepared and printed.
The Klopper Family History is on the Net at the TeaTree Gully District site - use Google.
the Bickhoff history is out of print but I have a copy - it is a subset of "The Naulty Family History - 150 years in South Australia, 1846 - 1996", Gerald Lally, (pp. 15 - 17, 42 - 55, 215 - 239 & 335 - 339.)
Make contact direct and I will arrange both the ancestoral trees, as I have them prepared to date - not complete.
