Aston means East Town. That's why it's a district of England, and not usually a name (though Austin and Ashton are, and probably come from the same word). I was named after Aston Martin (the pride of English automobiles), but my dad tries to deny this now, unsuccessfully. He says now I was named after a place, thinking that the car was named after the place so it's indirectly true, but the car isn't named after a place, it's named after a three-legged-race the founders had competed in. English people also ask if my parents were football fan's (there's a team called Aston Villa).
Bill Clinton's estate is the namesake of Aston Clinton, and Ozzy Osbourne is from Aston. I've only met one other person with the first name Aston, that was in Heathrow airport tube station, just after I got off train carriage 666.
