What a strange perspective your book gives.
I wouldn't be surprised if they were the names of Americans, but to say that they characterize "American names" is very misleading.
I've met:
Bear
Wray
Ionia
Darah
Shasta
Danean (spelled Deneen I think)
Kyle f was a small fad when it was a popular boy name but I've never met one personally.
Mare (nick for
Mary) and Rush are famous names.
