Who were the first two one term U.S. presidents?

The question sounds dumb, but the answer is acutally pretty interesting.

Who were the only two First Ladies, who never lived in the White House?

(There is a close third, who misses out because of a technicality.)

Who was the first president born west of the Mississippi River?

Heck, why not ask, who was the second?

Who was the first president to be born in a hospital?

Who was the first president born in the 20th century?

Easy one but what the hell...

Name the only 2 presidents buried in Arlington Cemetery.

Here is an interesting trivia question....

The glorious 28-week Presidency of James Garfield was first class all the way. His assassin Charles Guiteau put tremendous thought into selecting the precise firearm he would use to shoot the President: a .44 Webley British Bulldog with an elegant silver handle. Why was Guiteau so careful about choosing his weapon?

I believe that it had something to do with posterity, his legacy, that sort of thing.
Chuck suffered from, among other things, a narcissistic personality disorder.
Or maybe he just liked pretty guns.
It could go either way...

If it's something other than that, I'm always willing to learn.

Which president tried to buy Cuba from Spain?

I would have thought McKinley, before the Spanish-American War.
