Question re: ship lists

I'm not sure if this is the right forum, but I am hoping that someone may
have an answer.

If an immigrant who lives in "Germany Poland immigrates from, and the NY
ship document says they arrived from Glasgow, Scotland, even though they lived
in "Germany Poland", is it still most likely they emigrated out of Hamburg?
Will I be able to find them on either the direct or indirect list?

Thank you!
Rachel

Yes, most people from "German Poland" emigrated over Hamburg to America. See the web page: www. linktoyourroots.hamburg.de
