I don't know about the specific varieties you mentioned, but there are a lot of resources to learn more about local heirloom corn, beans, squash, potatoes, and other traditional crops. Find out who your nearby tribes are (or in the region you're interested in) and look into their food sovereignty programs to find out what varieties they're growing, whether they do seed exchange, spring plant sales, etc or just to learn about what they're growing. Our heirloom seeds are still being grown in our communities in many cases and/or are being rematriated from the institutions where they've been held for a century or more.
The best place to learn about native foods/seeds/anything is from native people. Here's an awesome link with tons of info:

(Based in Montana but very active Great Lakes chapter. Tons of great videos on YT.)
You might also find some information here:
