The Barque Sophie departed Hamburge 5 May 1866 under Captain H.W.Wendt and arrived in Port Adelaide Friday 24th August 1866 on board were:
Johann Hanschke aged 28 a Landmann(Farmer) from Turnow, Preussen(Prussia)and his wife,Christiane aged 28, 2 children, Anna aged 4 and Louise aged 1-1/2 .
Also listed but not with Johann is Martin Hanschke also a Landsmann aged 17 from Turnow, Preussen(Prussia).[My note it could possibly be A Brother of Johann]
Also from the same town was the Bartusch family.
all the best
