The last Ride Trivia Quiz asked "What Chicago street was named after a 7-year-old girl? Her father became mayor."

The answer is Cornelia, whose grandfather was subdivider Walter S. Gurnee. Gurnee was mayor from 1851 to 1853.

No one got this answer -- but we had some good guesses. Ada, like Cornelia, was named for the granddaughter of a subdivider. Berenice was named for a subdivider's daughter. But neither of those men became mayor.

A subdivider, if you're wondering, is someone who divides land into building sites.
