In doing more research on my family and the ship they left on, I find in the Hamburg Passenger list of departure April 25, 1865, 266 passengers from the province of Prussia. All destinations were to Quebec City, Canada port.
Ship was a sail and not powered by steam.
More as I continue my research on this passenger list.
