Yes, there truly is a person named Marshall Brain. I was born Marshall David Brain, and that is what's on my birth certificate. If you are ever up in the Springfield, Ohio area you will find a place called "The Brain Lumber Company." Both of my parents are from Springfield, and the lumber yard was started by my great grandfather Willard Brain.
Brain is a funny name to have. In school it meant I got a lot of kidding, but as an adult it is not so bad. It is a great conversation-starter.
I do not know the origin of the name -- it's funny that the How Stuff Works guy doesn't know how his own name works, but that's how it is (isn't there a saying about the cobbler having no shoes?). If you look it up in one of those "where your name came from" books it will say, "from a town in the south of France." And perhaps that is it. If any of you are big into geneology and would like to offer your thoughts, I'd welcome them!
