Local Flavor

A lot of "unusual" place names in the US can be traced to tribal languages, which is part of why weirdo local place names seem consistent locally but not nationally. The 50 US states are on lands stolen from over 500 Indigenous tribes, which explains the enormous cultural diversity across the US not adequately explained by textbook explanations that a handful of European countries shaped this country.

Even some of our state names are Native in origin and Wikipedia has a list. And here is me commenting on Kissimmee, Florida.

Although the distinctive culture of Louisiana is largely attributed to it being the only US state with substantial French influence, Louisiana Creole Cuisine blends West African, French, Spanish, and Native American influences and it also influenced Cajun cooking. 

Some Thanksgiving dinner staples, including turkey and cranberry dishes, are Native American foods. Below are select outtakes from the Wikipedia article Indigenous cuisine of the Americas.

Foods like cornbread, turkey, cranberry, blueberry, hominy, and mush have been adopted into the cuisine of the broader United States population from Native American cultures.

The most important Indigenous American crops have generally included Indian corn (or maize, from the Taíno name for the plant), beans, squash, pumpkins, sunflowers, wild rice, sweet potatoes, tomatoes, peppers, peanuts, avocados, papayas, potatoes and chocolate.

Since the first colonists of New England had to adapt their foods to the local crops and resources, the Native influences of Southern New England Algonquian cuisine form a significant part of New England cuisine with dishes such as cornbread, succotash and Johnnycakes and ingredients such as corn, cranberries and local species of clam still enjoyed in the region today.

Staples of Southern Cuisine, such as hominy, grits and cornbread, use Indigenous foods (corn aka maize in this case) and some originate with Indigenous preparation techniques. 

In short, we haven't bothered to really credit Native Americans for their substantial contributions to American culture, including unique place names and local food traditions. But if it's distinctly American, it's practically guaranteed to not be a direct import from European culture brought here by European colonizers and instead is a fusion of local Indigenous culture and the culture of origin of the colonizers and slave immigrants who came here during the time frame that birthed the US.
