Did anyone in the U.S. grow up speaking an Americanized/Anglicized/other dialect of a language?

For example, I know that in the Midwest, where I live, there is a dialect called “American Norwegian”. However, my family didn’t grow up speaking Norwegian or that dialect of it, so when I do learn Norwegian, I’ll be learning the European version. I grew up with some European Norwegian and a bit of Icelandic & Old Norse.
