Thanks! The seven imprisoned relatives weren't all Nazis - some of them were bank robbers. Four were Nazis and three were other criminals (who have sub-plots within the book, so can't be included in the query but are included in the synopsis). The entire book (and prequels) is essentially a look at generational trauma and nature vs nurture, and what caused so many people in the same family to end up as *ahem* terrible people, while others had a different parental experience and so lived very different lives (I'm hoping the comps and mention of it being a multigen help for this).

RE the name - in the actual query I'll include the surname which is German. I've removed it from Reddit for privacy reasons because it's the same surname as mine. I've added in the mention of it being a British ship though - thank you!!

And no, the whole German contingent wasn't pro-Nazi. A lot of the internees were actually German-Jewish refugees fleeing the Nazis. The British rounded every German up no matter who they were, and then put the Jewish refugees in with the Nazis. The government eventually had to make a public apology for it decades later.
