Help me with your perspective

[Anomalocaris]

40 chapters into the novel, the main character is slowly, throughout, revealed to be the last born Native American.

However, the catch is that he was born in Sweden after his family fled America.

I wonder, how does he remain Native American if he wasn't born in America? Does this mean he's just indigenous?

Up to this point, I've been getting by with referring to him as the last of his tribe.

I think depending on the context, there clearly are a number of different possible intended meanings for the term “native American”.

I think a few more likely meanings are:

1. Born in America but whose ancestors of recent past were from other parts of the world
2. born in America AND of ancestors who were here before columbus
3. Born not in America but of ancesters who were here before columbus
4. Born not in American and of ancesters where had been in America in the recent past but where from other parts of the world in the slightly less recent past.

In your case, it seems either 3 or 4 applies.
