The Irish Roots Cafe featuring Mike O'Laughlin is a very popular web site for anyone with Irish roots. Mike has been offering a lot of text information plus an audio Irish Families podcast for some time. Now he has added two new weekly genealogy podcasts for those who prefer to listen to the news:
Irish Families enhanced podcast, with photos and live links to the web: www.irishroots.com/podcasten/rss.xml (Quicktime required- click on live genealogy links while listening!)
Irish Roots Video podcasts (genealogy, genealogy books, history, song) www.irishroots.com/irishvideo/rss.xml
I'd suggest that you also check out all the other content at http://www.irishroots.com. It's a great resource.
