I'm taking it as a good sign.  One of the people I work with just informed me there is a Dillion, Mont.

Never before I have moved to an area with the same name as mine.  Did a little research and found out there is also a Dillion, S.C., and a Dillion, Colo.

Dillion, Mont. has to be the best out of the three.

Do you have a common name?  Or worse, a name that people commonly spell wrong?
