While people of all identities have and do quilt, what we know is mostly a European craft. Seminole Quilting is our best known American indigenous quilting form, from the Florida region. It is, basically, what our entire foundation of modern quilting is based on -- using sewing machines didn't just occur to us in the 1980s. I don't think so well suited for baby quilts, but maybe look at the designs and scale up to more traditional quilting sizes. Hawaiian and Mola applique techniques are also specialized forms.
Here's an NPR story that talks some about the issues and shows some lovely pictures:

There are many different native peoples in the Americas, very different cultures, very different climates. I would probably try for more of a feeling through my fabric selections, or pick more naturalistic designs, like maple leaves or maybe flowers. Applique can be great!
