I have tracked the Hanson family (Hanna, Hans, Jens, infant) from Gothenburg to Hull to Liverpool to Quebec (aboard the Allan Line SS Germany) but her husband and other son (Hans and Nils) were not with them. It's possible they were on a different ship direct from Gothenburg to Quebec (SS Josephine) or perhaps sailed a year earlier in 1869. I have gotten assistance from Swedish Genealogists to track down Hanna and her sons but have lost the trail of husband Hans and other son Nils. Their Swedish departure contract number is 149400.
I am writing a book on this family and trying up loose ends!
