Probably a connection I've not found.
I have the descendants of one family:

The party consisted of five married artisans, Ambrosius Theophilus Wilhelm Hartenstein (1811-1861), Johann Gottfried Haussmann (1811-1901), Johann Peter
Niqué (1811-1903), Franz Joseph August Rodé (1811-1903), Johann Leopold
Zillmann (1813-1892), and four single artisans, August Albrecht (b.1816), Ludwig Dögé, Friedrich Theodore
Franz (1814-1891) and Johann Gottfried Wagner (1809-1893).
The missionaries were designated at the Bethlehem Church on 9 July 1837 and at Greenock, Scotland, they were joined by Rev. Christopher
Eipper. The missionaries, their passages paid by the British government, arrived in Sydney in January 1838 in the Minerva.
The ones in bold all have connections in my tree.
