If you have Irish in your background, you may find something interesting at the website "Irish Central"...perhaps even if you are not Irish as well.
The home page is at http://www.irishcentral.com/
Although the site deals with a lot of modern day Irish topics, you can click on the "Roots" tab at the top of the page for things more genealogical.
For instance, one article gives you a list of the most popular Irish baby names in the US. You can hunt around for it (after all, that's half the fun), or go directly to http://www.irishcentral.com/roots/Most-popular-Irish-baby-names-in-America-101287949.html
