Defining "Norwegian American"

In the United States, we would define a Norwegian American as anyone with Norwegian ancestry. For example, the actor Michelle Ingrid Williams was not born in Norway, but some of her ancestors were, so she is Norwegian American.

I think this project is only for people who were born in Norway and immigrated to the United States -- is that correct? I was going to add some people with Norwegian ancestry, but I don't want to mess up your project. Should I make a separate project?
