Mine turns up "about" 1510 hits. It turns out that Mercule is an actual last name, and a real word in some foreign language (well, near as I can tell, seeing as I can't understand jack on those sites). Interesting, considering that I just threw together some random syllables for a character name.
If I use "Mercule Corin", the character's full name, I get one page of results. All are me. In any event, it doesn't appear anyone else uses my handle. Any gaming-related hits on "Mercule" look to be me. In fact, anything in English that isn't obviously someone's surname appear to be me.
My real name shows up a Colorado football player and some track-and-field hits. Odd, considering that I don't much care for sports.
