Ancestry find

And it's free (I'm pretty sure):
http://www.ancestry.com/learn/facts/

It can tell you (with very nice graphics) various things about your last name, including:
- Civil War Service
- Immigration Year
- Life Expectancy
- Name Distribution (UK)
- Name Distribution (US)
- Name Meanings
- Newspaper Headlines
- Occupations   (this one was particularly cool)
- Place of Origin
- Ports of Departure

I'm heavily into my family's genealogy, so, I find this sort of thing FASCINATING. And, who wouldn't?
