Is there any public domain geneology data sets available?

Question:

Is there any public domain geneology data sets available?

I am not looking for websites like ancestry.com, I am looking for the RAW data to use in a geneology application. Raw data means in plain text, or comma separated, mysql, or any other type of parseable data? Perhaps the government has some of these datasets?

Best Answer - Chosen by Asker: all databases are listed at cindi's... including gov sites, military sites, passenger lists, etc. all of these database's were written to work a little different, so just dig a little to find which one you seek.

if its on the web, its here:
