I have always wondered why Winston Churchill's last name was spelled with just one H.
Assuming his lastname was from a place called Church Hill, it seemed odd to me. So today I looked it up.
It turns out, his family is named after the village of Churchill in Oxfordshire. And in that village the old church is NOT located on a hill, and the name has nothing to do with that. Instead, the village used to be named Cercelle, which became Cerzhulla, which became Chirchehull, which became Churchill.
