What Was Samuel Clemens' Birthplace?

Some game show has apparently asked the question "What was Samuel Clemens' Birthplace?"
People are being sent here from various search engines, due to a fluke in Google's algorithms.

Samuel Langhorne Clemens was born in Florida, Missouri on November 30, 1835. The family moved to Hannibal, Missouri a few years later. Hannibal is the town that Clemens made famous, so I'm assuming they're using this as a trick question.

Here's a pre-emptive strike..... "How did Samuel Clemens get the name Mark Twain?" And "What does the name Mark Twain mean?"

The "marks" were the strips woven into a depth sounding device used on steamboats. "Mark One" meant approximately six feet deep. "Mark Twain", twain meaning "two", meant twelve feet or "safe water". Click here for a full listing of the divisions of marks. Anyone who rode on a steamboat would've heard these terms shouted to the pilot throughout a river trip, so when Clemens needed a pen name, Mark Twain seemed like a natural choice.

Those who love psychobabble have wasted a lot of ink on Clemens picking a pseudonym that means safe but not too deep.

Now, back to our regular scheduled programming. I apologize for whoring for hits. And I would appreciate it if someone could comment on why people suddenly want to know where Sam Clemens was born.
