I may be unique, but my name isn't.

There are: 6 people with my name in the U.S.A. How many have your name?

Well, I already knew there was at least one Eric Wilner in Canada, one in South America, one in, IIRC, Texas, and one somewhere in the midwest.

I, however, am the definitive one.

Apparently there are 2100 people in the U.S. who share my last name.  Most, however, are not related to me, as the name has only been in my family since my great-grandfather adopted it when he came over from Sweden.

There are 818,914 who share my first name.  Several have mustaches and mangle UNIX.

Update: there's also a doctor is Massachusetts who isn't me.
