Combining the volumes of work done by a prominent genealogist in my family, and my fascination with local history (wherever I am) has passed a lot of time for me. I love to research the "how's" and "why's" of cities and towns, especially in Iowa. For instance, Evansdale was originally just a rural collection of neighbors with flooding issues. They banded together, and an attorney from a town several miles away, Dale Van Eman, turned in the paperwork for incorporation to a judge named William T. Evans. The name of the town had not been considered, so they just named it when they signed the papers, using their own names, in 1947. Coincidentally (or not, I'm not sure), one of the original owners of the land was named William T. Evans. I haven't discerned if he was the same who later became of District Judge, or if maybe it was one of his descendants.
On a side note to this side note, I'd bet the town of What Cheer, IA has an even more intriguing story.
