Ron, the American Hornbeam, aka ironwood, is widespread in the eastern half of the US. It's probably a different type of ironwood you're thinking of, there are a few around the world. And, though I don't think it had anything to do with naming the town, the U.P. had three major industries, two of which were iron mining and logging (the other was copper mining). In the picture with Dan at his forge, the handle of his toolbox is made from ironwood, and I have a walking staff of ironwood.

Panache, completely forgot the sunscreen the first day, put it on the second but only once, then forgot about it again. Ouch!
