I see this a lot, no one has actual names, or any reference for names, that are legit Native American, varying among the tribes, for their characters.

Babynames.com and shit like that will give you names made up by white people.

However, I’ve got your solution.

Native-Languages  is a good website to turn to for knowledge on a lot of native things, including native names. If you’re unsure about the names you’ve picked, they even have a list of made up names here!

Please don’t trust names like babynames.com for native names, they’re made up and often quite offensive to the cultures themselves.

I love this site, especially the regional United States map. You can click on a state and it gives you the regions of the original Native territories, which is not only good to know but also helpful if you’re writing in an older setting and you want to be realistic about the region.
