Also, um, Africa.![]()
Oh woops, that's an obvious one

I don't mean any disrepesct but I didn't deliberatley leave out Africa and I do realise that there would be a lot who would have ancestry from there but I was only including countries that officially colonised these continents and (afaik, and forgive me if I'm wrong) Africans were only sent to America as slaves which is why I included it as Other.
Also I forgot about Italians but didn't know about Germans which is why the Other category is there.
Probably should've looked into the history more before posting.
Well, I obviously have a US-centric viewpoint when it comes to ancestry and suggested those things. If I were to talk about Canadian, Australian, or New Zealand immigration it would be slightly different.
As far as Africans being sent as slaves, that's not entirely true, but, for the bulk of history, is generally true. Still, many other nationalities were sent as indentured servants (which were basically temporary slaves) and Australia was populated by convicts (who also had no choice to go there). Africans, even as slaves, were still immigrants and make up a large percentage of the population of North and South America.
Plus, even Irish were sold into slavery when a 1690s law required any Irish Catholic owning land in the east of the island to either be subject to the death or slavery in Barbados, so it's possible to be Irish and a descendant for former slaves (much rarer, though).
Still, the interest in this thread for me is people posting, not the poll, so I guess other is fine.
