Grover Cleveland gets married

Grover Cleveland, the 22nd and 24th President of the USA, holds the distinction of being the only president to return for a second term after previously being defeated. The Democrat won his first election in 1884, lost (narrowly, and possibly due to voting fraud) in 1888, but then came back again to win a second term in 1892.

But Cleveland is interesting for another reason: he's the only president to date who had a wedding while in the White House. And his marriage was... unusual, to say the least. Cleveland was 49 years old when he got married 21-year-old Frances Folsom. She was the daughter of a close friend of his - and more to the point, after his friend died, he had become her legal guardian. Then married her. Oh, and he liked to call her 'Frank'.

It's probably fair to say that if this happened today, the press might make it more of a thing.
