Interesting. Nancy Nelson and I are wrapping up a history of Duluth's parks, to be published Spring 2017, and we have not encountered any mention of "Glenwood Park." The original official name of Chester Park was Garfield Park, but it was changed because everyone in town had already been calling it Chester Park and the Garfield name never took hold. (Lincoln and Garfield were the first "bookend" parks on either end of the early Roger's Boulevard—a portion of today's Skyline Parkway—and were named for the two assassinated presidents .)
