Fantasy names database

http://www.generatedata.com/ Can generate pretty good looking data for a variety of column types. Exports to a variety of formats, including SQL Insert Scripts.

There are websites which will generate fake names for you. I usually use fakenamegenerator.com but I think that only does one person at a time. identitygenerator.com has a tool which which will generate a large number of random names - and other personal information - downloadable in various formats.
