I've made changes to the description so that (I hope) it is cleaner to read, without taking away any information previously there. One thing I'm not sure about: do people prefer to see the legal names with middle initial rather than Jimmy Carter and Bill Clinton?
Are there any other "obvious" relations that would be worth noting?
Do people like seeing the vice presidents also listed under their respective presidents? (See the recent ones.) It may be a distraction if one is simply looking for a list of presidents.
